It seems like there are a few "specialties" one can do on here; have I forgotten any?
1) Blogging
2) Automated games (Fasting/Casting/Survivor/Dual/etc.)
3) Manual games (such as the Cmack311 's Idol Island I was just a part of)
4) Designs/Shops/Auctions
5) Frat stuff (not exactly sure, but I think it's a big enough component to be included on here)
