TanGRM – Tango Guestlist and Registration Manager

TanGRM (Tango Guestlist and Registration Manager) is the tooling I built to manage guestlists and registrations for tango events — the classic pre-event spreadsheet work of “who is coming, who paid, who is on the list at the door”, without hand-maintained Excel files. The Guestlist Manager is the part of it that matured into its own project.

TanGRM is deliberately single-organizer software: it runs the guestlists and registrations for my own events, and that focus is why it holds up — every feature in it exists because a concrete event needed it. The pieces that made sense for other organizers became the Guestlist Manager; TanGRM itself keeps serving my events.
