VSP, we talk about a lot of stuff all the time and bring ideas to the membership when we figure out that we can do it, how we'd do it, and that we can do it in a relatively short time. The chat room stuff isn't obvious in terms of how to implement it, although there are a number of technical solutions. None of them is simple to implement, so we weren't sure that we could do it at all, much less quickly.
We'll be posting a bit more about possible changes as the summer progresses, since some of us will have a bit more time to work on things. We'll certainly ask for input as we need to make choices about what to implement. But, just because implementations exist elsewhere on the web doesn't mean that we'll be able to get it done, given our possibly more limited resources (both in terms of funds and the time availability of those with expertise).
