User Comment Module won't allow "approve" comment permission

I'm trying to use the User Comment Module (6.x-2.0) to allow bloggers to moderate comments on their own blogs.

I've got the module installed & configured and it adds a "delete" permission (next to each already-approved comment) for the role + content type I want to grant access to, but it won't grant "approve" permission even though I have it selected in my permissions for the correct role and content type. Is there something I'm missing somewhere else?

I've been testing it out with comments made after installation in case that matters.

And is it supposed to send an email message out to the approver? It's not doing that either.

Thanks!
