Sugarcube Corner, where you can talk about things not directly linked to the show, such as merchandise, meetups, and so on
Equestria Girls, for discussion about... well, y'know, Equestria Girls...

Everfree Forest, for all non-MLP discussions =)
Cloudsdale Colosseum, where there's games and random stuff
