I was never much for Chat before, I spent many wasted hours on IRC (yes, I am that old) so I am not as much on the Discord as my son is. Though I have used it a little for rps it does help in arranging things for an rp with separate channels for OOC, characters, and diverging story threads. For that its great, but as in many things, if its not your thing then threads and posts here work just as well. Its all in what you are comfortable with. While it would be nice to have it back, I actually started using it a little before it went down, it wasn't as much a driver for me as others since I came to write, then pretty much went on with my day.
Though if it came back I probably have the itch and would make the odd comment to scratch that one.
