I can set custom user fields for permissions across groups. But I can't seem to find how to restrict built in fields like "Home Page" - which is an instant source of spam and one I wish to restrict and/or turn off. It would be nice if this could be done by user group too, but I don't see a specific setting for this and perhaps I missed it. Is there a control for this field?
@Mike - Thanks for pointing it out. And you're also exactly right in that it will probably be wide ranging. @Brogan - thanks for the suggestion. While that will technically work, I think I'm going to look into developing an addon this week to manage these fields by permission groups so that I don't have to worry about future user groups (and what could be a growing list of template edits.) Generally I'm locking off fields the other way around for areas which probably no one but an administrator or maybe a mod/supermod may be able to access.
