Many GMR players were using Slack as the preferred communication platform for several years. Couple of years ago we attempted to move to Discord, but there was not enough interest in the community, so that was shelved.

As of April, 2020, we have shut down our Slack and moved to Discord. Come join us: https://discord.gg/nAaW2d7

Why did we move from Slack?
- Slack has a message history of 10,000 messages. It is quite useless for discussing civ games that can last years.
- Discord was designed around playing games, and we are playing games.
