Well, this is a rather illegal event and by notifying Richt you really put him on the spot.
All you give him is time to prepare, with lawyers guns and money. This is not a fight that a discussion board junkie can win. It's a fight for the NCAA. Compose all the proof possible, times, dates, names, hopefully a picture or two, submit it directly to the NCAA, and copy both the GTAA and the Clarke County police department. Also copy CNN. I have a contact at CNN who used to be the editor for the Technique, who'd be a good guy to get it in the hands of, to make sure no Georgia grads intercept it and trash it before it makes the headlines.
Do NOT give the UGA Cabal time to prepare. They are pros at dodging this kind of stuff, they have judges in their pockets, and they're going to be very willing to break laws to bury this. This needs to go to the NCAA and the media.
All you guys who saw it need to exchange personal info, write down in detail your own account of what happened, put that all in a letter, cosign it, include any other details you can (please please please tell me you have a cel phone photo) and distribute it to the authorities directly. Including CNN (national media as opposed to local media) is extremely important.
Edit:
Actually, let me shoot an email to my buddy at CNN (he also works very closely with the GTAA, writes for the alumni newspaper, and is friends with Wes Durham) an email and get his opinion on what to do with this. He would know much better than I.
