http://garrysmod.com/wiki/?title=Admin#Dedicated_Serverscopy the add admin layout thing what i show under my post under dedicated server into your garrysmod/settings/user txt make shure the spaces and everything are perfect. When you make your self admin make shure your name is the first one on the list then everyone elses. You can put your name in both admin and superadmin and restart your server and you should have admin client and admin. Also clear out garry and user2 and you have to have your steamid and everything perfect id say try starting from the "user" at the top and put everything under it
"Users"
{
"superadmin"
{
"amburgers and wootbeer" "STEAM_0:0:6724541"
"Snoop-Stabby-Stabb" "STEAM_0:0:3555994"
}
"admin"
{
"amburgers and wootbeer" "STEAM_0:0:6724541"
"Snoop-Stabby-Stabb" "STEAM_0:0:3555994"
}
}
this is how mine looks but the spacing after the { is diffrent copy the spacing from the example on wiki the spacing is probally as big as indenting a paragraph but get it from the dedicated server users example
