Thank you for your reply. So, I think I'll get a subscription and install CB Redirect for the deadline matter. But I also needed another function, that is a way for users to submit their application (contact info, files in the profile gallery etc...) even before the deadline, simply by pressing a button, let's call it "submit your application". So, if they press this button, they cannot update their data anymore (or all the fields in a tab), all fields become "read only" and only administrators can edit them. If possible, users receive an email confirming that their application has been successfully submitted...
Sorry for asking too many questions, but I just wanted to make sure (before subscribing) that I'll be able to do what I need to do on my site. Thanks
