Registration opens two to six months ahead and the curated events fill within minutes of opening, with waiting lists managed by hand. Role balance means a registration can be accepted for one partner and not the other, which produces a distinctive and stressful travel decision that no other row in the catalog has.

Local milongas as the true social unit, event Facebook groups, teacher and school networks that function as lineages, and the registration lists themselves, which are public and read closely. Dance at a local milonga on a fixed weeknight, take workshops from visiting teachers, host visiting dancers on sofas, and travel in small self-organised groups.

The Buenos Aires festival and championship in August as the circuit's pole star, the long-running European marathons and encuentros that occupy the same weekend every year and are named by their city, and the summer seaside festivals. The milonga, a tanda and the cortina between them, cabeceo, the abrazo, the ronda, leading and following as roles rather than genders, codigos, a marathon, an encuentro, the DJ as a named and judged figure, floorcraft.
