The Members list should be sorted more sensibly

User Interface, UX
Summary: Eric points out that the sort order of the Members list is, at best, unobvious. Change it to something more useful (eg, Display Name order).
Ideally, this should be a table with headers with click-to-sort. But for now, let's at least make it better.
