Well, with submitter registration I could allow submitters to log in, see the status of their submits (no more "was this reviewed yet" emails), see how many of their sites are currently listed (no more "was this site listed" emails), avoid email address on the submit form altogether, allow submitters to edit their email address, allow better mass mailing to all submitters, do a better job of checking for multisubmitters, and a shitload of other things.
I could even allow submitters to see rejection reasons back to their first submit.
I'm just wondering how many LL owners would be turned off or on by this feature
