No-login sign-up sheets for potlucks, class parties and volunteers

The problem

Organizers of potlucks, school parties and volunteer shifts need a list people can claim slots on. The biggest free tools show ads on every sheet, and removing them takes a paid plan or add-on. Group chats and shared spreadsheets end up with three pasta salads and empty shifts.

For: PTA and room parents · Church and club organizers · Office party planners · Volunteer coordinators

Why now

The Census Bureau reports that 75.7 million people, 28.3% of Americans aged 16 and older, formally volunteered through an organization between September 2022 and September 2023.
