Registration opens on a Monday in March.
The event manager set up four types in February: member, non-member, student and speaker, each with early, standard and late phases that switch on dates she chose, so at midnight on the early deadline the prices change without anyone logging in.
A delegate registers as a member, picks the Tuesday afternoon workshop and the Wednesday morning panel, fills in a structured dietary field and a wheelchair access field, and pays through the connected provider.
The workshop room figure she recorded is forty; at thirty-eight the chooser shows two places left and at forty it offers the waiting list.
