Regarding Pro Chat Rooms:
despite several requests for information about their product features, I received no answer from them in years. I had sent them specific questions which are important to vbulletin webmasters.

After trying again this week I received several rude responses, which in the end left me without any answers. I am not sure if this is consistent with their general support attitude, but if it is, then Pro Chat Rooms is to be avoided IMO.

That was posted in late October, 2012. Things haven't changed much. I currently have 5 or 6 support tickets outstanding, none of which have been answered...

I will say one thing about ProChatRooms though, the source code is very open, although the internal commenting of it is quite poor. There is NO written documentation about it -- the only support I've seen is that it is "user supported." And not much of that, either.
