Okies, I know the main reason I'm not on anybody's lists is because I only recently rejoined and before, even though I was a member for a very good amount of time, I still wasn't very popular. >.< But, anywho, my list:
22sa: He was nice then and now. He was the first person and still only to PM when I rejoined. He's pretty concerned with everybody here at PC, and I think that's pretty awesome.
Lightning: Before PC was restarted, I know I liked her art a lot. She was pretty nice as well.
Diana (Not sure of who she is now, okay, so I don' remember): She was and still is an all around nice person in my book, and she seem involved with the community.
PokeTrainerCarol: To me, I kinda always thought of her as PC's most popular person. Almost everyone had/has something nice to say about her. Gah... If only I could be like her, lol.
More soon...
