Shophere and Hart_House are correct you can use myphpadmin
or similar program to edit a link before approve it. It is not to bad unless the field you want to modify is the catagory that they are
submitting to. On my new site
http://www.island-search.com I have had around 100 site submissions in the last couple of days.
I would say half of them I had to modify the catagory. I got to the point that I approved the submission to what ever catagory they submitted to and then went in uning admin and modified the catagory. I am sure some sites were wondering what the hell was going on. Hey if you want to use indexu as Hart_House and some other have tried nicely to tell a lot of folks on this board for all intent and purpose most of the time you are on your own.
