Task 172 assigned to alex by tim

Now that People are only listed if they have biogs:

1) not sure that this is evident to you if you DO have a biog (e.g. why is someone NOT listed in the People page...) Don't know the form of language to use for this...

2) I am missing the fact that I can't find out who has signed up recently... We could have a "recently joined" listing (as a list of names - no avatars/bios?) on the homepage and/or people page, or simply add to event stream, though I'm concerned that the event stream gets crowded out with this kind of trivia...
