I'd like to add one thing, which is that sometimes the chat interface is frustratingly difficult to use, resulting in me sometimes not noticing that someone has messaged me, sometimes in mistells on my part.
So if I don't respond, maybe it's because i've given up scrolling up and down in the window, clicking, clicking, clicking, trying to find a relevant message from someone. Maybe it's because I just didn't see the message. Maybe it's because I'm just overwhelmed with four or five people trying to talk to me at once.
My apologies to anyone I've possibly offended because of this.
