Challenges

Hi - It would be great if there either

A. There was an email before the end of the month for what the next months challenges are

2. Change the timeframe of the challenges so they have the same start time, regardless of when you sign up

C. Allow signups before a challenge actually starts so the last week of a month say, I can sign up for the following months challenges.

Since there are not always challenges each month, it stinks if I forget and check a couple of days late, and then miss having workouts count towards a challenge.
