I will update this page with when additional information (links, dates, etc.) becomes available.
1) Buy a Membership to Sasquan 2015
In order to vote for the 2017 Worldcon site, you must have a supporting or full membership to the 2015's Worldcon.
2) Wait for the Site Selection Ballot to Be Announced
The Sasquan 2015 Site Selection Ballot is currently available here. Follow the instructions on the document to vote, especially if you plan to mail in your ballot or submit it via email. Candidates are also listed on that document.
3) Pay Your Site Selection Ballot Fee
The fee to vote is $40 and can be paid online via Sasquan's Site Selection page (the payment system is NOW open!). You may also pay the fee at Sasquan or via Check or Money Order (in US funds) with your paper ballot (see address below).
This fee automatically transfers into a supporting membership for the winning bid. The winning bidder may also extend additional deals for full memberships after the selection process is over.
4) Download the Print Ballot OR Go to the Site Selection Booth During Sasquan 2015
Worldcon does not currently allow electronic voting, so all ballots must be submitted at the 2015 convention OR by mail or email.
The print ballot is available here (as noted above).
5) Submit Your Ballot
If you are not attending Sasquan 2015, then you must print, fill in, and mail your ballot to the address provided by the deadline OR email your ballot to firstname.lastname@example.org (for those who pay their fee online).
To mail your ballot, send it to the follow address:
Worldcon 2017 Site Selection
c/o Joni Brill Dashoff
PO Box 425
Huntingdon Valley, PA 19006-0425 U.S.A.
All mailed and emailed ballots must reach the site selection crew no later than August 10th, 2015 at 24:00 PDT. Send it well in advance if you are concerned about delays.
That's it. Pretty easy, right?
