<@MjnMixael> committing to SVN is easy. If you make a file change, you should notice it's green checkmark change to a red exclamatiom point. It does this for the whole hierarchy of folders too, so you can tell very quickly where changes were made on your computer.
<@MjnMixael> it will also do this if you delete a file
<@MjnMixael> If you add a file to a folder, it won't show anything at first
<@MjnMixael> once you've made all your local changes (like adding a script or editing a script), go out to games/freespace2 and right click on BTA1-SVN folder...
<@MjnMixael> near 'Update' you'll see 'Commit' and press that. It will then give you a list of all changes, deletions, and additions to your local copy of the mod. Select whihch ones you want to commit and press OK.
<@MjnMixael> then you're done
