Not sure if serious or not because you're a few scrolls from the section lol.
Go to forum (Obviously) then scroll down. The Roleplay Chat section is where members discuss roleplays they're working/check who's interested in them.
Below Roleplay Chat there are other section called: Jump in roleplays, Fantasy Roleplays, Modern Fantasy Roleplays, Horror Roleplays, Misc Roleplays and Fandom Roleplays.
When you click on each section there will be a box explaining what's allowed in that section AKA rules. If you would like to be apart of a roleplay that interests you, click on the "Sign up" section located at the top of the genre you're in.
To post a roleplay, just click on that same "Sign Up" area and post it there with all the information it needs. People will stroll along and find it, but don't expect a huge load and don't let it put you down! Another section to see if people are interested in your roleplay, go to the "Roleplay Chat" section and post a thread about an interest check.
