Disallow adding "guest" user to group

[apeisa]

Intuition says no - will probably only add confusion.

"Nope" says my intuition also. There's group "Everyone" already, no more of those are needed (that's what adding "guest" to a group effectively does, right?).

[teppokoivula]

Agreed. I wouldn't allow this, at least not by default.

[apeisa]

Ok, I change this to a bug - it's currently possible, and I cannot real use for this in any scenario.

[apeisa]

Or actually - enhancement...
