Hallo.
RP Protip: Don't join an RP if you can't handle the basics. Being in a roleplay is a commitment. There will be rules and minimum deadlines and stuff and you
need to be sure you can follow them, or at least stay in contact if you are busy. Nothing is worse than a player who dives in and then can't commit, because it messes up the roleplay (and sometimes straight up kills it) for other people. Also make sure you can handle criticism and being corrected. You
must be able to make changes without getting offended or quitting. Trust me, game masters don't crack down on people for kicks or to abuse power. They don't tolerate power abuse here.
I might suggest looking into
1x1 roleplays first. It's extremely diverse. There's more room in 1x1 to adjust for new people, and it'll get you used to the format and flow of the site. If you want to get into a group, Casual is the most active of them, but you have to be prepared to commit if you join one.
So yeah, look around. Ask questions. Be flexible. Players here are patient and will work with new people if they're not aggressive and rude. If you can handle that, you'll have a blast.
