Why? Maybe they don't even know what the a is, or maybe they don't like the colours to fit, maybe they like a sig with rainbow's coloursm, doh. They can only say "My vote goes to Fugitive", so I would probably win. Joking.
Seriously, I don't think we should count the poll votes, only the posted votes should be counted, and the 30 posts minimum rule is great. Voters should only write "[name] gmv" or just "[name]".
And the Shoutbox was great for polls because I can shout there about the poll and soon more votes will come, so I won't have to bug all my MSN list to go there and vote for somebody.
(I made it bigger because I just want the damn Shoutbox back)
