MicSheet

MicSheet gives open mic and poetry slam hosts a shareable sign-up page for each night, where performers grab slots from their phones. Full nights roll into an automatic waitlist, weekly nights can repeat on their own, and hosts can mark a night cancelled. Hosts can reorder the lineup, check people in and track no-shows, and every sign-up builds a contact list of performers. It's free to use, and Founding Hosts can get Pro for life for a one-time $29, limited to the first 150.
