Where can I edit the "Length" Of the e-mail address That is in the Submission Form, for new Links? As it seems to have a default character length, that needs to Be changed. As I tried it with an e-mail example" test_test_testers@domains.com And it kicked it back. the I tried it without the "_" and with added Characters, and it still kicked it back, so I know that it is not the "_" that is causing the problem. Then I tried it with "not as many characters" and it worked fine.
I do not know what you mean by kicked it back but the email max length is 100 Chars which is more than enough for any URL not only email, see this email:
