Yay, a mockup!

Some notes:

By default, people are sorted first by whether or not they've been contacted
(uncontacted first), then by date. You can also sort purely by date (reverse
chronological order) or by name (alphabetical).

The person's name and profile picture link to their profile. The email address
is a mailto: link.

The date is the date that they clicked the 'I wanna help' button. "Wants to
help" is an optional extra field that the person can fill out, that appears
after they click the 'I wanna help' button. (UI mockups for that functionality
forthcoming.)

When a person is checked off as contacted, the project maintainer who checked
that button is recorded as the person who contacted them.

The "Remove" link removes the person from the list of wannahelpers.

Hopefully that's all reasonably clear!
