Multiple Admins on Dedicated Server

I recently rented a dedicated server, and I was wondering if it’s possible to have multiple admins on at once. I edited the users.txt file for me and my two friends to be admins so we can spawn admin weapons and stuff, but it makes the first one of us to connect to the server admin, and the other two aren’t.

Is there a way all 3 of us can be admins at the same time?

Thanks for any help.

Use an admin mod such as ulx and through rcon type ulx adduser yourname superadmin. Do this for each of your friends. This will allow for alot more admin functions that just weapons and will let you easily manage your server.

Alright thanks.
