The voting deadline is December 9, 2011 at 23:59 (GMT in Europe, MST in North America). Votes may be submitted by mail or via PayPal – presumably the latter at this stage of the game.
That also leaves you a few hours to inspect Hats For TAFF, a joint fanzine by the TAFF 2012 candidates.
Voters will choose between Warren Buff, Kim G. Kofmel and Jacqueline Monahan for the next TAFF delegate. See more info and full instructions on the official ballot for the 2012 TAFF race here [PDF file], as well as the necessary e-addresses for PayPal. The minimum donation is (US)$3 or £2.
