Comment 7 for bug 81369

I think we can do better than the screen cap I have mocked up here. The subordinate checkbox to limit the emails to preferred languages is too wordy, and the focus of the form becomes unclear. I could try to co-opt the 3-state boolean radio buttons [1]:
Team Answer contact
Landscape Developers (*) No ( ) Yes ( ) Yes for preferred languages only
Ubuntu Team (*) No ( ) Yes ( ) Yes for preferred languages only

[1] yes I know that is a oxymoron, yet Zope provides the behavior for required widget that may not have input.
