I think it's about time to do this. A separate category on forums for roleplaying. With car related things. Examples: "Engine swapping my Roamer", "Cherrier sets new Hirochi Race Track record for hatchbacks", "eSBR 500 0-60, 1/4 mile, top speed run", car selling, people's vlogs. With videos and pictures attached like in the mods and comment section.
There was such a thing already but got removed for an unknown (to me) reason so the only way to roleplay is to either join a private Discord server or just live without it
