I vowed to keep Experimonth: Mood registration as simple as possible by only requiring name, phone number and email to sign-up. 

The name because I have a theory that communities where folks use their real name have more accountability.  In this way, all participants go by their first name and last initial except for co-hosts (full name) and readers who are not participating (whatever they input on the comment form).

The mobile number and email were required for the text messaging and weekly mission communications.

The downside is that I don’t have too much information about the participants.  I hope to fill in the gaps with questions on the blog and requests to fill out profile information, but the only thing I’m assured is name, phone, email.

This graphic takes advantage of area codes — an implicit but likely inaccurate location measure given the numbers are mobile.  It’s still interesting, and I hope it will prompt the group to put their zip code info in their profiles so I can more accurately chart their participation.
