Version 1.5 has been released with the following changes:
- The script is now using a more accurate query to retrieve buddy list information. The previous version didn't report some buddies under some circumstances. This has been fixed.
- Using the shownopermission function for unregistered users trying to access the script.
- The list of buddies no longer has a trailing comma.
To upgrade, just upload the new whobuddies.php into your forum directory. The new version can be downloaded from the first page of the hack thread.
Credits to FireFly for the updated query!
