There has to be a deadline for host bids, so at the moment, that deadline will be 19:00 EST (UTC-4) on Tuesday, August 9th. Host bids are recommended to, but do not necessarily have to resemble past bids. Here are some examples of previous winning bids.
The winning bid from WBC 36, Chromatika.
The winning bid from WBC 35, Nova Anglicana.
The winning bid from WBC 34, Saintland.
Puppets are allowed at a maximum of one per nation and must be confirmed by the master nation, but in the end, it is up to the host whether to include them or not.This post also acts as a signup for Nova Anglicana.
