Filled out the submission form, but wasn't sure if I needed to press the "submit" button, or the button to create a new project. I chose the latter, and it took long enough that the submissions were closed by the time I finished (at exactly 3:00 PM MST).

I don't see my project in the submissions list, but I also don't know how much lag time there is between submitting it and seeing it.

How can I confirm my submission, and if I didn't submit, can I please get a "do over" -- you can check the time stamp on my "Do or Die" project to confirm it was created before submissions closed.

there is no "submitted" tag at your avatar, guess not :(

I vote you get a chance to submit!

The jam FAQ suggests that if something like this happens, let the leaders know on discord and they'll help you get it sorted. This needs to be done no more than 2 hours after the deadline though, so try to do this asap.
