Hi there, AngelBell!
As you can see, I'm also fairly new myself, however, I would say I am acquainted with the site now. If you are extremely curious, I would suggest you give the name of the RP. For the most part, if you're joining a forum RP, your character will need approval by the Game Master of that RP. However, if you made the character with some thought and grammar, it should be accepted.
While I would love to suggest an RP for you, it really depends on your favorite type of thing. If I were you, I'd click on the Roleplay tab at the top, and just browse through whatever else looks interesting. Otherwise, you might be interested in the Multiverse, an RP where all characters are canon, and you can usually find people willing to RP.
