It is something i've looked into, but on a LOT of other sites i'm on, its a neat novelty for a short time, but after a little while, no one winds up using it.
Also, any valuable content or discussion is lost forever... if the similar discussions were carried out in the forum, the data could be retained for future use.
It is still something i'm looking into adding, but there are a few other mods to the forum that i'm thinking will be way better and more useful than a chat applet.
Always open to thoughts and opinions though, so let me know what y'all are thinking
Oh, by the way, this should be in the "Feedback Forum", so i'm moving it there 8)
