I see. I'm not on this server enough to call myself a true 'regular' I think, but it has been extremely useful for me on many occasions when I've had oddball or highly technical issues that fall outside of Epic Dev's "intended" use cases for engine features, or just things that simply aren't explained properly (or at all) in the UE Documentation.
Many times, just having active people to bounce ideas for solutions to those issues off of has been enough to get me in the right direction and get the problem solved on my own. So it's not always been a simple "I have question - please give answer" situation.
This is why I originally suggested a forum-based format. I've found that occasionally someone will reply to a user's post without tagging them, which complicates things further when trying to keep up with a discussion about a topic. More commonly, you get someone asking a question, then another asking another question, and another question... By the time a decent number of people are able to see the channel chat, Question 1 has been buried 100's of lines of text up in the chat history.
