Wow, I can think of several things to talk about... XD It was fun back in the old days when there weren't so many members, and it was easy to get to know people. I miss the way it was after I first joined, and Kairi/Abby would always seem to be on the site helping out with something. She was one of my favorite friends, but I've never really talked to her since she left.
Anyway, dare I mention the infamous original "Do you have a crush on anyone at PC?" thread. It was like the only spam-filled thread that most people seemed to like. XD I was involved in many crazy RPs with my friends Sayuri no Hoshi and 100marios... It was so hilarious, lol.
I'm also randomly remembering the annual proms, and all of those other events that Dizzy would always come up with. XD Those were kind of silly, but fun.
And of course, I remember being one of the people selected to be a Moderator after I took one of those old Mod tests/surveys about 4 months after I joined. O_o; I guess that now it's good that they don't pick staff members like that... But then I ended up becoming a Super Moderator, so I was happy~! I just had to resign after so many things came up in real life.
