TMD, the Tango Marathon Directory has been around since 2009, and it has evolved since then in many ways.
As a dancer you can find out about events for advanced dancers willing to travel.
A lot of the details are only visible to people who have an account on TMD (Why?). Accounts are free, and it just takes a few seconds to setup. You’ll get a searchable and sortable tabular overview of events and djs.
As an event organizer you can post your events (for free). Events will also be shared automatically via its email newsletter, reaching over 1500 people directly. Historically, the focus has been on tango marathons – but encuentros, festivals and milonga weekends (? terminology) are welcome, too.
