Is it possible to have the new tag set based on the Mod_Date instead of the Add_Date? I would like for the new sites to be flagged and sorted to the top of the list based on when I add them instead of when they are submitted.
In Links 3, you can set this up automatically in Setup/Misc Options - at the bottom of the page is a setting for link_validate_date, setting it to 'Current' will do what you want.
