I don't exactly know if it is posted allready, but I fixed the little bug that prevented users to edit or delete their own shouts.
In vbshout.php find:
Code:
if ($Shout['sid'] != $vbulletin->userinfo['userid'] && !can_moderate())
and replace it by
Code:
if ($Shout['s_by'] != $vbulletin->userinfo['userid'] && !can_moderate())
This line is found twice in the code. Once for editing and once for deleting a shout.
