Becoming a Member of WSFS
The World Science Fiction Society is an unincorporated literary society. The only way to be a member of WSFS is to join the current World Science Fiction Convention (Worldcon). There is no way to join WSFS without becoming a member of the current Worldcon.
Rights of Members
There are two main classes of membership: Supporting and Attending. You can think of a Supporting membership as your actual membership dues to WSFS. The Attending membership includes a Supporting membership, plus the “convention supplement,” or cost to actually attend the annual convention of WSFS.
Supporting members have the right to receive the current Worldcon’s publications, to nominate and vote on the current year’s Hugo Awards, to nominate on the previous and subsequent year’s Hugo Awards, to vote for the site of the Worldcon two years from now (subject to paying an additional fee that is the supporting membership to the two-years-hence Worldcon), and to propose changes to the WSFS rules through the Business Meeting. Supporting members cannot attend or vote at the Business Meeting
Attending members get all of the rights of a Supporting member, plus the right to actually attend the Worldcon itself. Attending members may attend the WSFS Business Meeting, make motions, debate, and vote on proposals.
Other Membership Types
The current Worldcon is allowed to define other types of memberships to their convention. Some of these membership types may include the membership types listed above, but others (e.g. “Single Day Admissions” or “Babe in Arms”) may include only admission to the Worldcon without membership rights.
The WSFS Business Meeting
The only way to change the rules of the World Science Fiction Society is through the annual Business Meeting of WSFS, held at the Worldcon, and open only to Attending members. (Supporting members may propose changes, but cannot attend or vote on them.) Any proposal approved by WSFS Business Meetings in two consecutive years becomes part of the WSFS Constitution.
