I'm thinking we're just going to go with the static field in the user record
for Internet email addresses. After decades of messing around with this data
model I'm inclined to keep it simple this time.
I was able to fit 16 addresses (with pretty long names in them) in 512
characters,
so that's what we'll go with.
If you have a test system built from the git repository, I'll commit but
not publish so we can play around.
Also remember, this is prerequisite to the idea of published/unpublished
addresses in the GAB. We'll tackle that next, once we've got the requirements
dealt with.
