Today (January 31) is the deadline to get a membership (attending or supporting) to Sasquan, the 73rd World Science Fiction Convention if you wish to nominate works for the Hugo Award.  You don’t have to nominate today, but your membership must be purchased by today in order to do so.  Supporting memberships are $40 US.  Information about costs for citizens of other countries is on the website.

Keep in mind this is nominating for the Hugos, which will establish the final ballot.  The membership deadline for voting on the final ballot is later in the year.
