MidAmeriCon II

QUICK FACTS ABOUT WORLDCON
The World Science Fiction Society (WSFS) does not run the Worldcon. Each Worldcon is run by a different group of people who ‘bid’ for the honor to host it as far out as 5 or 6 years in advance, sometimes even longer! It’s like the Olympics or a World Cup.
While some cities have hosted a Worldcon more than once, the group running it changes each time.
Worldcon members are members of WSFS. Think of WSFS like a club where you have to pay annual dues to remain a member. Each time you purchase a Worldcon Membership (excluding child and day passes), you are a member of WSFS for that year. If you are a member of Sasquan (2015) and also purchase a membership for MidAmeriCon II (2016) you are a member of WSFS for 2015 and 2016.
Every member of Worldcon/WSFS in a given year has the right to nominate for the Hugos, vote in the Hugos as well as vote for the committee and location of the Worldcon two years from the current one.
Hugo nominating only is additionally offered to members of the prior and following Worldcons.
Voting for the location of the Worldcon two years from the current one requires you to pay an Advance Supporting Membership Fee, which gives you an automatic Supporting Membership in the Worldcon/WSFS for that year, no matter which location wins.
