maerk, you aren't helping. My case is that I would want some users grouped in one role and others grouped in another role, but a few individuals as part of both. And no, roles don't inherit capabilities of lower roles. The hierarchy is a bit artificial as a user_level is assigned to each role and is only significant for the capability to "edit others' posts" as I understand it.
I find it mentioned that WordPress supports the multiple role functionality being implemented, but has anyone used it or detailed how one must modify the user role in the database to reflect more than one role? If there is no plugin that manages it, I'll modify the DB myself but I need to know how to list the roles.
