New to uMod here myself and looking to see if the following scenario is possible.

Created a new group for moderators, want to grant moderators permission to grant the whitelist permissions only.

Is this possible? Thanks in advance!

That isn't really a question specific to the Whitelist plugin, but rather permissions from Oxide itself as it is what ultimately provides the commands to grant permissions and such. Each command in Oxide has a matching permission for it, so for oxide.grant, the permission would be oxide.grant. So if you want moderators to be able to grant permissions (I'd advice against this), you'd grant that command to them.

There isn't really a way to limit which permissions a group can grant really, outside of a plugin being made that intercepts and checks for which permissions they are allowed to control.

For permissions info, see https://umod.org/documentation/plugins/permissions

Thanks I kinda figured as such looking at the config but wanted my moderators to be able to whitelist people but not grant permissions outside of that. Thanks for the quick response!

I'll probably be adding something to this plugin to handle adding to the whitelist via a command or whatever outside of the permission.
