CM forum uses an animated background starry by standard, but that tends to eat a huge amount of CPU usage, meaning keeping forum open is gonna cause ingame stuttering.
The SS13 community is wild and having your CKey public in anyway is a bad idea. It doesn’t matter what you write, SS13 players are barely literate and will choose to misinterpret what you say then get mad at you for it.
Don’t use the same CKey to play on different servers either, it’s just not smart.
I shouldn’t be having to teach about internet security but also having your usernames/CKey matching on multiple websites also isn’t a good idea. Use different usernames for everything
