Yes you can, easily.

I have a mini-plugin for this somewhere around here…

Here you go:

<?php

/*

Plugin Name: Delete Own Post

*/

function delete_own_post($retvalue,$capability,$args) {return ($capability=='delete_post') ? bb_current_user_can('edit_post',$args[1]) : $retvalue;}

add_filter('bb_current_user_can','delete_own_post',10,3);

?>

Note that they can only delete for as long as they can edit.

Meaning after the 1 hour default, no more delete.

But you can change the timeout in the admin settings.
