Welcome to Smogon! Take a moment to read the Introduction to Smogon for a run-down on everything Smogon, and make sure you take some time to read the global rules.
Yeah, UU is much better than OU IMO. In OU you see the same teams over and over. With UU, it's much more diverse; no two teams are exactly the same. I highly recommend it.
Agreed. I'm also thinking of getting a Treecko soon. It's always held significance to me, as my first Pokemon game was Ruby and I picked Treecko as my starter. Pretty much swept the game with it, it was like Lv. 81 by the time I migrated it, lol.
