As an admin, I've been watching everyone participate, and these are my comments on each candidate to help you decide.
UNCheels has been very helpful to me in updating the draft as a mod, especially while I've been busy with setting the stuff up in Madden.
I also have noticed max has been online a lot, and he always posts, which is great for this forum.
Catspajamas helped me with some autopicks during the rookie draft, and has been very reliable in this league with trades etc.
RpAaVtEsNS (patstown) has been posting a lot, and has some admin experience.
And mksadng has been a great poster, and a very active moderator in this league.
Touchdown! Jesus (lebronzoom) has really helped me out, and although he has been gone recently, he is still a great trade mod. He also has lots of admin experience.
Still deciding on who to vote for, I view zoom and mksadng as the favorites, cats and patstown as close second place, and UNCHeels as the dark horse here.
