wouldn't that be per item? than approving it would be easier..
I checked the submit.php to see how it stores the items, and it stores them into the submissions table, whereas actual approveditems are stored in (for news) news table
so it does not have to do with a 1 for approved or 0 for not approved (as some blogs for example do)
thanks for your answer anyway

EDIT: see the source of submit.php self, and the source of submissions.php (in adminstration folder) to see where it stores approved items (the submissions.php is the script that has the data in it that can approve items..)
http://t2b.110mb.com/showsource.php?file=submit.php for the submit.php
http://t2b.110mb.com/showsource.php?file=submissions.php for the submissions file
(yes, i did secure this script o othat only these two files are allowed)
