Hiya Morallygray!
EVENTS! . . . start going to as many scheduled RP events as you can! Check the forums here for advertisings and there are some Discord channels to look into as well! Will post a link to that thread too.
When I first got started RPing, it was a bit slow at first, but after I started going to Events and running into the same people over and over, things snowballed from there!
Check out these Discord Servers for some RP action too!
