If you put your mind to it, anyone (and everyone!) can be an admin! even you!
I actually have about 1000-2000 posts, mostly in the debate forums (Hi Sin!). I mostly keep a low profile and help when required.
On a serious note...
Series Vs Series.... I found Korra to be far superior to Aang.
just seemed way more mature.
Finale vs Finale... though....
This fight alone made the Aang finale superior.
