Hey Green Gambler If you need to delete lots of feature requests or inappropriate requests just go into phpmyadmin and delete the entries en masse from the table.
100 at a time if you need to.


path is yoursite.com/cpanel
login then go to php myadmin (bottom right I think)
click on your database
find the table eg feature_req - click on that
then click browse
then - click checkall and the big X
and all your worries will be over

cheers

ps make sure you've got the right table first and always backup b4 hand
