Is the Chat on the forum really necessary? It seems to me that it's now redundant compared to past times, since everybody who is into this sort of thing (chatting) is on Discord. True the Chat is not really harming the website by merely existing in its little left-hand corner, but it may be worth it to perhaps move it to a more noticeable position in the forum, perhaps popping up fully expanded on the left side of the screen. A little intrusive maybe, but it may encourage more use and you could ex it off. It might even cut down on redundant threads.
As of now, it is only being used by bewildered new users who treat it as a interactive technical support. If that is how you want it, then at least have the decency to rename it "SE Technical Support" and nominate me and Marko S as Space Engine IT Specialists.
