Yep, it's a good idea! The one year anniversary will be April 20th, by the way, so it's a long way off yet.
If you like we can start thinking of some award categories, and maybe we can make some nominations for the polls. Then run the polls during April maybe.
Here are a few possiblities. For PokeBase we can have things like Best Question, Best Answer, Best overall user, Best moderator (including the experts), Best moveset suggestion.
We could also do general Pokemon ones if you like, e.g. Best Pokemon, Best Move, best pokemon of each type, etc etc.
I will look into perhaps getting a poll script and adding to this site, but otherwise do you know any good websites where you can run online polls?
