Comment 11 for bug 18351

Why would you want to set up groups right after creating an user? The tool is designed to avoid you this painful process, by choosing the default profile. You may need to change profile for an Administrator, but not more.

There can obviously be a group tab, and that's not too complex, but I don't feel like it's the highest priority. So I won't do it myself for now, and anyway it's too late for Lucid. I'd much prefer we find better ways for use cases - most people should rarely need playing with groups anyway.
