Where have all the challenges gone?

I remember when I first started MFP, I hooked up w/ a group of GREAT people who did all kind of challenges. We had Biggest Loser, Who can lose the most in a month, Christmas challenge, New Years Challenge, etc. Now, I do not see any challenges any more. I love a good competition, and it was wonderful motivation to get up, get out, and do something! Am I missing them or are we just not having them anymore, because I want them back!
