This addon is unreasonably simple...
All it does is adds a player to a user group.. just like ulx adduser does.. however it does not save said player to the user.txt file. This means that when the server session ends, they will revert back to whatever rank they held before.
to use it, simply type
ulx tempadduser <user> <group>
Even if they log out.. unless the server has changed maps or restarted they will keep the temp group. However when the server restarts or starts a new map they will not have the temp group anymore and will be whatever they were before.
NOTE: In the request for this addon the person requested a timed group. I know how to make this, but it would require more time. I MIGHT do it later. for now, or until someone else decides to take up this task, this is the best substitute.
