how do i set permission on my server to groups 

oxide.grant group {GROUPNAME]extendedrecycler.use

thanks but i am still having problems getting it to accept the command
i only wish i had someone that could get all the mods on my server to work as i am very new to running my own server if you know anyone that could do admin work on my server could you let me know thanks

Sadly I am too busy to directly help out, but if you want you can always send me a DM on Discord, and I usually answer within 24 hours, dependant on how my RL day works out.

(I install commercial/industrial solar systems in Africa, in summer (now) it gets to 100+F heat so some days the sun beats me into the ground and I don't even touch my PC)
