veto's are for trades (not drafts). i think there's a 2 day window for the rest of the league to approve/ignore or veto a trade. for example, let's say i draft Gorappolo b/c but TTT convinces me to trade him to her b/c that's her boy. and b/c u have a better trade offer for me (or to be funny), u decide to veto it. not sure for many veto's kill a trade tho for what we have set up.
you're asking too many questions. i'm starting to think u are a pro and a hustler pretending to be a n00b. i got an eye on u!
(j/k keep the questions coming.)
