Raul,
Thanks! The chat system that cichlid-forum uses is phpopenchat. It is a very good system but I have a few problems with it.
First, most of the install docs are in German as is the code. I don't read German.
Second, it requires the use of a second database on the mysql server. This is easy for cichlid-forum as they have a dedicated server. We are on a host (at least until we get big enough

).
Thirdly, it doesn't integrate into phpBB2 very well, yet. Cichlid-forum's website is highly customized so the integration of phpopenchat is more easily done. We rely on phpBB2 for our design. Any add ons have to integrate with that source code. Again, until I have enough time to "re-do" the site.
The above notwithstanding, I am in contact with the phpopenchat folks to see what can be done.
