The gold, silver, and bronze roles are ones I created, not created by a plugin.

By higher and lower, what I was referring to is one role having more capabilities assigned to it than another role, just like how the Administrator role has more capabilities than the Editor role, which has more capabilities than the Contributor role, etc. Thus in the example, the Gold role has fewer capabilities than the Administrator role, but more capabilities than the Silver role.

A user assigned a role that has the list_users & promote_users capabilities can see and promote users assigned a role which has fewer capabilities, but cannot see users assigned the same role or users assigned a role with more capabilities.

I hope that helps what I’m saying make more sense. Thank you for your help!
