For the Hugos, I have a supporting membership (being upgraded to attending). I can nominate any eligible book that I feel should be on the ballot. (GCA is one of two books I plan to nominate.)

Once the final ballot is announced in early April, we have till a set deadline to vote on who get the hugo and then the administrators tally the numbers and announce it at worldcon.

Just making the ballot is a major accomplishment. I hope to see your name on it.
