Membership Upgrades Now Available

Hello everyone who pre-supported the Seattle Worldcon bid or voted in the 2023 site selection–

Thank you for your patience with us while we made changes to our registration system. We will spare you the gory details! We are now ready for you to upgrade your membership to an attending membership in the convention (WSFS membership + attending supplement) and complete registration. You should have received an email from us describing the steps to follow on March 1. After sending the email, we discovered a glitch which may have caused the email to be delivered to your spam folder, so please check there if you did not receive it. We think we solved that issue going forward and will have better luck with the reminder email.

If you think you should have received the email but did not, or if you have any questions, please email

All the rest of you, please stay tuned for an announcement about registering for Seattle Worldcon 2025 before a planned price increase later this month. We want you to join our celebration of fandom in the Pacific Northwest. Let’s skedaddle to Seattle!
