Email users who haven't logged in in a while

[ErinCall]

Track users' last-logged-in date and update it whenever they view a page.

Make a worker that runs on a cron job and checks for users whose last-logged-in date is more than two hours ago. Send them an eMail packet that says e.g. "where you been? We miss you!"

I am starting work on this issue today.

Two questions about this issue:

1. Do we want to email users whose last-logged-in date is more than two hours ago or is that supposed to be weeks/months?

2. Should we exclude users who have pending applications or whose applications have been rejected?
