If you register a forum account, you get a modify button...if not, the forum has no idea who you are to authorize you being able to edit your post.
I'm sorry. I'm normally consider myself a reasonably nice guy.
Normally.
However, I'm tired of lazy people SEEMINGLY not reading. SEEMINGLY expecting to be handed the easy answer to becoming an admin on a silver platter.
This has nothing to do with you not creating an account.
Qiuck easy answer.
No, you're not right.
Little bit longer answer.
For now, I suggest NOT editing data/ULib/*.txt files.
In fact, delete ULX/Ulib files just for now.
Then, edit your garrysmod users.txt (NOT ULX) like shown here
http://garrysmod.com/wiki/?title=Admin#Dedicated_ServersIf once you follow those instuctions, which are STRAIGHT from Garry's wiki on how to get admin access on a dedicated server, you get a message when joining the server that says something like "[Superadmin] - <playername> has been recognized as an admin"
(Ok, I forget what it says exactly, but its similiar to that...
THEN, and ONLY then, would ULX recognize you as an admin.
If you get recognized by Gmod, then by all means, re-install ULib/ULX.
