Mod Post!
Welcome to Please Pick Me! The place where RPGs come to YOU! Please, feel free to tell your friends about us! The larger the directory, the potentially better we'll be able to help.
The unfortunate limit is that Livejournal itself only permits inclusion into five categories, as noted on the main page. My suggestion is that, even if you are grouped into a general category such as "general anime" or "vampires," that your profile still include within itself which shows/fandoms you are currently interested in playing for. For example, if you're under "general anime," you could include a list such as
Inuyasha Cardcaptor Sakura Blue Gender Akira
That way, if a prospective mod walks in and looks at your profile, he or she will have a better idea of what you are interested in, and if they're looking for a specific fandom, they'll have a much better chance of finding you. It's a thought. ;) Ultimately your profile can be as specific or inspecific as you like.
Also, if anyone needs to be placed in different categories, please let us know!
