A Dr. Who fan!
Like Imveros said, you can keep an eye out for openings in already in progress PbP, though you will likely have to pick up the character already in play rather than create your own. If that is okay, I know of two games that are in need of players - Kindred Bond and Tabula Rasa. I'm not sure that Ryo means to recruit to fill the vacancies, but it couldn't hurt to ask.
And welcome!
