you can also PM the person running the game (usually but not always the person who starts the thread) and ask if you can get in, this works well for games that are already underway that interest you. Please show respect for the game however, and read a fair amount of the thread so that you'll know what kind of character would fit the game best, ie in a pirate game, a ninja just wouldn't work (as ninja's and pirates are natural enemies, and kill each other on sight).
