Submit an entry you were already drafting but did not have ready by the entry deadline, a couple of weeks later.
It also allows to to start new drafts and submit them at this later date. All subject to your having sufficient entry credits.
Without this option your entries must be submitted and complete by the entry deadline, as is the case with most awards.
Note that categories available at the time may be different from the selection available now, and that the guarantee of inclusion in the Peer Awards Book may no longer apply if your entry is nominated for certain categories.
