Yeah, they can.But I don't think most of them will do it, and even if they do they are not going to get 7 votes.Sorry my bad. Btw, I cant see who voted for whom. In that case, self voting is possible.
I'm loving Meet's idea. Create 3 discussions in the SG and quickly ask each member to post his choice(no self voting). Also alert the unaware members via updating the thread title. First person to achieve 4/5 votes shall be considered the skipper.
Me, who else!Greens, you know who to vote for.
No you can't.This could get a bit unreliable 'cause this on the poll site you can vote more than once.
