The MinMaxForums have (mostly unofficial) Discord and IRC channels, for those prefer their communication slightly more real-time than a forum. You can find myself and a number of the other MMX regulars hanging about, chatting away, and otherwise being vaguely entertaining. It's also a good way to get ahold of the moderators if you need help.
For the modernists: Join the Discord
- run by myself and Alcyius
For the classicists: IRC is at #MMXGeneral on irc.rizon.net - run by Bozwevial
