Folks, do you think it might be a good idea if this site checked urls for duplication when they are submitted? These urls could expire in 3 months or so..thoughts?

It does do this, though it checks for an exact url string match. So, say, a trailing slash would make a difference.

(edit: Or it used to... I thought it did.)

Resubmission can be useful, maybe a week to prevent accidental dupes.
