Start here, with this blog post: http://inuscreepystuff.blogspot.com/2010/09/majora.html
When you reach a line of ==============, go to the bottom, watch the first video, then go back up, and repeat.

Since then, Sep 17th:
-a few coded messages were left on jadusable's 'recent activity' log
-they were hints, 'think about it' and '.net' translated
-and then finally a coded url linking to an ancient tech support forum
-http://www.showeq.net/forums/archive/index.php/t-3355.html here. nothing from here is part of the arg. I think it just happened to fit.
-of note is the .net structure, and someone saying you shouldn't have done that
-two and two put together formed a new site: http://www.youshouldnthavedonethat.net/
-And this is when it really turns into an Alternate Reality Game.
-At first it seems like an innocent cultist site. But you start to see things. References. Of course the first thing is that it's devoted to the moon, and there are children in the moon in Majora's Mask.
-if a cultist site can be innocent
-Anyway, other things are: The bookmark icon, is Majora's Mask.
-Mouse over the admin 'Drowned's avatar pic
-The banners for all the pages are references to many areas in Majora's Mask: Swamp, Mountain, Sea, Canyon, City, Apocalypse.
-Then you start getting into the creepy, the hidden stuff.
-On the 'about' page, Rosa is mentioned in a special thanks list. Rosa is a character from Vampire: The Masquerade: Bloodlines, and is featured in a video on Jadusable's account, mentioned in TheTruth.rtf. She talks cryptically about the future. The video was posted one year ago. Tags on the video reference the BEN videos.
-The Prototype video also has some importance. It too has related tags. Prototype's main character is called Alex after the blackout. On the Main Page, it's mentioned that Alex has gone missing after the Blackout.
-The Banner on the search page, if you right click and go to the image properties, there is associated text: "Do you honestly think you can escape me?"
-In the source code for TheTruth login page, there's the text: "It's what they DON'T want you to know"
-On the press room page, there's hidden text found if you select everything: "Like little lambs. The man is smiling."
-On the theories page, there's the usual doomsday theories, and one unique, original one, featuring a 'Kelbris.' I'll get to that later.
-On the guestbook on the main page, there are some posts from some 'cultists' that were there already when the site went live. One asks for an admin to check the contact page: something is not right about it
-There's nothing wrong with the contact page itself, but people did some guesses with urls
-http://www.youshouldnthavedonethat.net/index.php/contact/ben/  This was the first discovered.
-A countdown to 'The Fourth Day.'  Kind of a reference to the last video Jadusable posted, stating that 'The Counter Resets.' The music is a Reversed Happy Mask Salesman's Theme, which was featured in the second video.
-http://www.youshouldnthavedonethat.net/index.php/contact/drowned/  The next one found was this.
-It's a clear reference to the Giants of Majora's Mask. The coded text on the title reads: "MY EYES... THEY TOOK... MY EYES..." The music is a Reversed Ikana Canyon Theme, which was featured in the first video.
-And of note is the image's filename. It's 'Kelbris.jpg'
-Kelbris was said to have been found electrocuted. I don't know if this is of any signifigance, but Link was electrocuted a bunch of times in the first video, but also burst into flames.
-No one's been able to crack the login. Reports indicate it might be fake, leading nowhere.
-And that's all that's been discovered about the site, as of Sep 17th, 3AM EST

Since then, Sep 18th:
-Two hours before the countdown was to finish, a new page on the site showed up: http://www.youshouldnthavedonethat.net/index.php/contact/drowned/ asking "Should you know what question to ask, the gate to truth will be opened:"
-People asking about Ben were told that he had ascended, and his body was never found.
-People asking about the two contact pages were told that he couldn't see them.
-People asking about Rosa were told that she was his sister.
-People asking about Alex were told that he was their strongest warrior.
-People asking about what Majora's Mask had to do with anything were told 'nothing. why?'
-Of note is that Ifrit's real name on the About page is listed as Rodney R., in the emails it was Matt HUBRIS.
-When the counter reached one hour left, the main page updated with a new song playing in the background, a faster version of the reversed Happy Mask Salesman's Theme, and Drowned's post dissapeared from the page.
-As the counter neared the end, some replies were answered with 'hang on someone keeps knocking at my door'

-And then... Nothing.
-Nothing's happened yet, as of 8:50PM EST, aside from the site itself breaking.
-Jadusable's account has posted an excrept of lyrics from WHO'S THAT KNOCKIN' by The Genies. A reference, perhaps, to the people knocking on Ifrit's door.
-At 9PM EST, a video response to FREE.wmv was posted, called fj6rt, by TheMissingLink, real name: Alex. fj6rt was at the title of Ifrit's contact page. The title of the page has since changed to the url for the video response. The video features Adult Link in Ocarina of Time playing the Song of Time in front of the Moon.
-At 9:20PM EST, Jadusable, or rather, BEN, posted thetruth.rtf on /x/ again. The image posted was of the Happy Mask Salesman, named 'The Father.jpg.' Hopefully confirming that the Salesman is, in fact, the father.
-http://www.youshouldnthavedonethat.net/ went down for maintenance. It doesn't exist yet.
-We've all "gone back in time."
-Jadusable's account updated with: "What makes you think I have a Twitter? So desperate for answers... all it has done is thrown you off further from the course..." Proving once and for all the JadusableBen twitter account is fake and not part of the game.

SPECULATION
-They don't know us anymore.
-They don't know we know them.
-Everything will happen again.
-We still have Ifrit's email, back to figuring out what to ask him again. Probably this time warn him as well...
-We can WARN him that someones comming... Remember Rosa?
-"DONT OPEN IT!"
-We could possibly save Chris as well, as he Ascended on the "Second Day," after FREE.wmv.
