Worldcon 2028. The most important event at smofcon each year is the fannish q&a, where seated conventions and groups bidding for worldcon, nasfic, or smofcon make presentations about conventions. As a result, montreal in 2027 is the only currently active bid for the 2027 worldcon.
Announcements and presentations from the worldcon bids for 2028, made during smofcon 41 (the convention about running sf&f genre conventions) on december 7,. Memberships are not available from the worldcon web site, because each worldcon is an independent organization, so you must contact the individual worldcon directly.
