When you submit an entry to a contest at The Rookies you will not be able to edit the media that was submitted. *
Think of it like an email. Once you send it, it's done. There is no turning back. So take your time and make sure everything looks good.
There are clear reminders and checkboxes to make sure you understand this is going to happen. The good news is that if you have created a great entry, you are able to select Save Draft. This means that your hard work won't be wasted. You can come back later and continuing editing your entry directly from your Dashboard.
* You can edit the entry featured thumbnail, title, description, software tags, skill tags, contributors and adult content settings.
