Well.. I see you've started a Harry Potter one.
From the top of my head, i thought of Lord of the Rings. I can't see how Twilight can be a roleplay, really. Such a shame, because i know how much you love it >;]
Eeerm. You could also start your own little HoN. Problem is that it's not majorly popular. Which is also a good thing, in it's own sense.
OHH You could also do a Heroes roelplay also. Y'know, the show with all the people who have special powers. That one would involve a lot of forums though so that might have to be made into a sub. I'm just thinking aloud here, by the way. You don't have to like anything i'm saying ^^
Ermm.. If i think of anything more then i'll post here and let you know wink
