Do you RP often? Do you like the idea of having a website dedicated to each of your characters to throw tons of information, images, etc onto? Do you want a community where you can easily find other RPers alongside this convenience? Well you should totally join RPR! I've been on there for a long time, and even though I don't always get on the forums, it is a really fantastic place and I do encourage people to try it. I have some amazing friends there, despite my apparent inability to converse on forums xD
There are some neat contests atm still going on for a little while, too. So join in on the fun!
It is definitely my favorite site! I have also tried f-list and character hub, but for me it is so convenient, easy to use, and unlike hub it has the community in the forums you can interact with. It has also grown considerably since the beginning, and the administration seems to care a lot about keeping up with the place. I definitely recommend giving it a shot!
