every board I know that's tried it has rapidly ditched it, for some odd reason, behaviour tends to be ghastly, and you very rapidly get trolls and troublemakers (even amongst erstwhile peaceful boards)- it then needs 24/7 monitoring................ 
 
Personally, I don't use chat systems, I find them annoying - with the forum system, you can take your time over a reply, or carry on a damned near real time conversation anyway!
