So far, and I admit to not having a working copy running yet, but so far this looks like a great piece of software. I could nitpick some details, but I won't because (a) there is no way I could make this happen on my own and (b) what's the point of nit-picking free software that's in beta release?
My target audience - a non-profit club - hasn't asked for this but so what: I am the webmaster and I know this is what we need. This software tucked inside phpbb will give my club virtual meetings. I expect that when the dues-paying members who simply can't make a physical meeting due to the distances of travel required, hear of this option they will realize what I already know: we NEED this!
So anyway thanks for this extremely phat code. May your path to a non-beta v1 release be greased with unpredictable opportunities!
