Hi Mark,

So much simpler ~ *way* better!

For clarity, I'd suggest changing
Advanced Options to
Advanced Preferences (Optional)

Someone suggested that folks choosing No Mail should have to provide a verified email address so they can be reachable by an owner (Special Notices). In that case No Email except Special Notices would be great wording. Eliminates concerns about privacy at work.

Thanks!
Linda
