You might want to write a short story or two and posting them in the Storytelling forum (don't forget to link them to your signature). I linked a few of my stories and poems to my signature, and was able to connect with people that way. This provides readers with a hint of your writing style as well.
While you're at it, you might review a few stories and provide feedback to those of interest. Again, just something to start a dialogue. I'm not sure about anyone else, but I haven't done an RP with anyone I didn't get to know a little first. But, I'm fairly new and that may not generally be necessary.
Of course, it might be also be a good idea to consider the story requests from other members. Nothing wrong with a little quid pro quo.
