Add notification when a new problem enters the top 200

[davghouse]

The 200 most-solved problems will probably change over time. Once the present 200 are solved and active solving stops, it would be nice to be notified when a new problem enters the top 200.

How about a weekly notification on Monday @ 9AM Eastern Time when the current set of solved problems doesn't contain the top 200 problems? In the notification, include links to the missing problems, their implementation and concept difficulty ranking, and their current position in the top 200, ordered by position.

Example 1:
Email subject:

1 problem from SPOJ's top 200 needs to be solved!

Email body:

#198: https://www.spoj.com/problems/ANARC08H/ (I: 9, C: 19)

Example 2:
Email subject:
