I know one of his questions though, being with the Damagelogs, that's something that you have to edit manually. If you're using it from the same place I got it, just go to garrysmod\addons\TTTDamagelogs-master\lua\damagelogs\config\config.lua and add in your ranks following the format (THEY MUST BE EXACT)
And, following with JamminR said, to grant that access it's in the !menu > groups tab
