Considering the fact that I've been here off and on for ten years, I'd say the memories I've had. Why? Because if it wasn't for PC, I would still be the useless little n00b I was back then. PC has taught me a lot, and that's why I came back here again. It holds most of my memories, much more than any other forum I've been to. Sure, they aren't all good ones, but they are still memories. Ones that have taught me a lot and helped me become a better person. I finally overcame my past and came back here. The people are nicer, and there isn't anyone nailing the new people anymore either. The staffers are all nice and supportive even though a few of them I don't talk to because I've had bad experiences with them.
That, and yes, I also love pokemon lol.
