I keep missing events, I want to stay up to date.
EDIT: I don't want common ones like Bulbapedia, Serebii, or Wikipedia, none of those are helping me.
I'm not sure what events you're talking about, but I'll do my best.
Sanctioned VGC Tournaments
I would highly recommend Nugget Bridge or the official Pokémon website.. NB will ususally have all necessary info in teh appropriate thread, while the offical site will have a better catalogue.
Serebii mate. (Sorry, but it really is the best of the best when it comes to these.)
