The RSUGP system has been activated due to a request from Blues_gurl. The system goes somewhat like this:
Maximum RSUGP: 10000
You will be able to view your bar from your profile or under your username when you post. Only admins can give out RSUGP, so no-one will be able to unappropriately use it.
Admins, only give out or take away RSUGP when there's a good reason for it.

Is there any use for RSUGP or is it just like the rep bar?

By the way, nice name change

Thanks, Blackmetal . Anyway, RSUGP is pretty much like a rep bar, except the more you get, the more chance you have of becoming a mod or admin.

Can you lose your administration if you get too less RSUgp?

Maybe, that's yet to be decided. RSUGP can also be swapped for RSGP in the market section.
