I own a small community that I founded in early 2016 with some friends. We have been going on for around 5 years now and have always kept our very chilled back & relaxed approach towards everything we do. Feel free to hop into my Discord server if you wish to join us!
The community was started up around a Garry's Mod server, but we have since closed that server down and now the community is not focused around anything, instead it is now more of just a casual place to chat and make new friends. Although, we have recently started up a Minecraft server if you enjoy playing that game. However, my Discord server still gets the most attention, with roughly a dozen always active members, around 150 current members and nearly 500 to have ever joined in total.
I also have a Matrix chat room if you prefer messaging with better privacy and security, the address is
#viral32111:matrix.org. Do note however, there are signifigantly less people in it compared to the Discord server.
Finally, I do also have a Steam group. However, the chat is never used and I stopped posting announcements in it some time ago. It is very dead and only exists because it cannot be deleted, so do not bother joining it.
