The window for submitting new pre-proposals opened on April 1 and will close at 5 PM on Sunday, April 15 or when we hit the limit of 25 eligible pre-proposals, whichever comes first. When you submit a pre-proposal to the submission mailbox, you will very quickly receive an automated reply. If the window for submission is still open, the automated reply simply reiterates information about due dates and procedures. If the window for submission has closed, the automated reply will clearly state that the limit has been reached and you may try again in the next cycle. You can always use the “Contact Us” function on the website to send an inquiry, and you will be answered as soon as possible.
