Greetings!
Again I can not believe what a wonderful website this is, and am so happy to be here, but I think I may have found an unusual bug... I have posted my profile URL on facebook to share with my friends, but facebook renders "profile;u=" to "profile%3Bu%3D" in the url and apparently the form takes exception to this and redirects to the main page. I apologize if this is just the natural order of how things work with the form's software or if this bug has been reported before.
Admins: If this was not known, I dare you to search your log of caught bad links to see if others have done this too =P
