Re: Admin in ULX - Read, follow, understand the readme.txt files. They're located in addons\ulib and addons\ulx if you followed install directions properly.
Make SURE you downloaded ULib and ULX from our ulyssesmod.net site..don't use garrysmod.org for admin mods (many get uploaded with modified code)
We also have FAQ site (Frequently asked question)... 'how do I make admin' is probably one most viewed.

You'll have to read the instructions that come with each mod, or, find the original release thread that those releases were made.
