I you don't like the vb option
Time Limit on Editing of Posts in post
#6
you would have to edit two file
ajax.php and
editpost.php
Find this code
Code:
else if (((($forumperms & $vbulletin->bf_ugp_forumpermissions['candeletepost']) AND !$isfirstpost) OR (($forumperms & $vbulletin->bf_ugp_forumpermissions['candeletethread']) AND $isfirstpost)) AND $vbulletin->userinfo['userid'] == $postinfo['userid'])
And replace with this code
Code:
else if (((($forumperms & $vbulletin->bf_ugp_forumpermissions['candeletepost']) AND !$isfirstpost) OR (($forumperms & $vbulletin->bf_ugp_forumpermissions['candeletethread']) AND $isfirstpost)) AND $vbulletin->userinfo['userid'] == $postinfo['userid'] AND $postinfo['dateline'] < (TIMENOW - (10 * 60)))
