I'm just saying, that I have seen this exact discussion before about implementing chatboxes, it's an understandable concern but in practice it does not harm activity. As for the constant moderation demand, I don't think that's really much of a concern at the current level of activity you guys have. Unless you anticipate a lot of rule breaking/bending for whatever reason. Maybe you have testy members. I think chatbox helps contribute to a more stable memberbase by encouraging consistent activity, the high turnover rate of conversation encourages checking in on the forum more often to see what's up instead of maybe popping in every few hours or so. It increases accessibility, and that's important for keeping new peeps. Just my 2c
