There was some talk a little while back about what to do if/when discord gets to the point of being unusable and a small list of potential alternatives to look into should that become necessary was come up with, which I am now porting here for ease of access into the future.

Main potential alternatives:
FramaTeam (it's French but by a major Open Source proponent company, not all translating is done at present)
Guilded (one of the major discord competitors. Not preferred because they're likely to do the same thing discord has been over time)
Matrix (Urus says this one is promising)
Slack (supposedly decent)

Possible Intermediaries for while organizing a platform jump on the off chance Discord goes down catastrophically
The DTG Forums (these do exist even if we almost never use them)
SB Forums
Steam chat (unideal for various reasons. Not good except as a last resort)
