Add an in-game command that directs players to this thread: https://www.seriousgmod.com/threads/ttt-information-and-content.53912/#post-566791. Command could be something like "!content." Would help new players who don't have the SGM textures. I can't imagine this would be too difficult to implement.
pointless if no staff on, point is so people can find the content if needed - not so they have to find a staff member to find it for them
I think that !content would be better. Just like deathrun has !bhop. We dont know every time someone is having issues with content
