Read up on some guides, a few are pretty old but still give valuable information that you can use.
Stay away from organisations for now, you’ll want to build yourself up before attempting to join any of them, and avoid them whilst roleplaying they can either get you in trouble with Staff or you’ll make a lot of enemies very quickly.
I go by the name of Violence, I won’t be actively on the server for a while but I hope you enjoy MonolithRP
My tip for you is that you try to familiarize yourself with the monolith game mode and to introduce yourself to people with how you want them to perceive you. Just be cautious about breaking rules and have fun in rp which is the most important thing.
