Suggestion needed on what I can do here

Hi All
i have an aviation related site that uses WWF and I was wanting to incorporate some way of having a chat/discussion etc on a specific topic with a guest speaker say once a month and I am unsure of the best way i could incorporate this into the forums/site.

I thought of using a chat room but the only alternatives I know are ASPChatNow but I believe it is buggy but I could be wrong plus the mod of this in a thread here is only for Access and I am using MySQL. The other is ConquerChat but I believe this is limited to 10 users per room.

The other thing about a chat room is that a question is asked and whilst the special guest is typing a reply more questions are asked and everything ends up in a muddle but perhaps a chat room is the only way to go.

Any suggestions or ideas is really appreciated

Thanks MadDog - does this work with MySQL?

Thanks MadDog - I am giving it a bit of a play and have installed it plus used the code to list the active users in the Chat Room per the post at:

Is there a way that:
1. only registered members can go to the chat room
2. If a guest tries to go to the chat room they are met with the forum registration page
3. The login is bypassed and the members forum login name is used

Thanks very much for your help thus far
