I know that some forum software has modular programs that can be added to the existing website (don't know about this software though).
You can have it available all the time, and also it can show how many people are on it at that time so people will know when would be the best time to go on.
Having a meet up time would be a good idea as that way we can ensure that it will be used. 8pm UK time is good as then US residents can also join in if they are online in the afternoon. 8pm US time might not be so great as that's between 1am and 4am our time... and I need to go to work in the morning!!!
