Rebellion Roleplay is an excellent roleplaying forum. The staff are friendly and approachable and happy to help with any problems. Everyone is warm and welcoming, not to mention happy to help out any of the new members that may need some guidance. Everything is run smoothly and moderated at all times and at the same time the vibe is very relaxed. There's very few rules and you can roleplay just about anything from Lord of the Rings Fandoms to Murder Mysteries and other roleplays. Out of many of the mature sites out there, this is by far once of the best I have came across. 10/10
RRP is a multi-genre 18+ RP site where you can pretty much do whatever you want to. Who doesn't like that?
