Hi Trevor,
Since writing this in 2005,
There are several add-on chat modules available for this forum software, but I haven't tried any of them. If there's sufficient interest, we can try one out and see how it goes.
I’ve found that having modifications to the standard forum makes maintenance much more difficult. I've gradually been reducing the number of minor modifications to make upgrades and so forth simpler.
So now I’d be reluctant to add on a chat module unless there’s a real demand for it. A monthly meeting wouldn’t require any modifications, just a pre-arranged time for people to be online.
