I am not sure if this forum has this capability: however, some forums enable you to see the IP address for which the accounts were created. Plus, the IP address is logged on every post. If this forum has this, it would be a great help. I'm not sure though.
Some free forum software you'd really want to check out is found at
http://forum.snitz.com/ It is highly configurable, and there are many benefits.
I'm not sure if it is too late: but, you could possibly move the accounts and the like. Pardon my ignorance on this one, i'm not sure if that is possible to move all the accounts and that: but, it was just a thought. I do not believe that this forum software has the rep system as this forum does. At least I've not seen it in use on the forums taht use this software. That would be what I'd hate. I think our rep system is cool.
And about that George guy, what in the world is the sense of replying to help threads with lack of common sense answers, especially if he doesn't even have the answer to begin with? I'm usually the kind of person who is very level headed and tries to find the good in even the worst people in reason: however, this is nuts!
