For anyone thinking this, just integrate discord! Best chat ever! Plus you can moderate all messages via your phone or whatever device you use discord on. 

Besides it not following "forum" usernames and actually following discord usernames I don't see much of a problem. 

I don't use much integration due to how many thing's I'd have to change, my members are just required to disclose their usernames on a private form that posts to an Admin+ forum page.
