I am going to participate in LD for the second time. I would like to ask more experienced participants about some points.

Last time, a week before the jam started, the semi-finals started, where 16 of the 48 themes were chosen. 2 days before the start of the jam started the final, where everyone chose the winner from 16 finalists. Now there are 4 days left until the start and the semifinals have not started yet. Do I understand correctly that this time the principle of selecting the theme is not the same as at the previous jam? And how was the selection procedure at previous jams?
