If you haven't joined a challenge this year what's stopping you?
There's a challenge for just about everything! Although I think I'm going to start a challenge, challenging you to not join a challenge... just kidding
Challenges with UPDATE are new or entering a new phase, which means you won't be behind the learning curve.
Let me know if I've missed any simply by sending me a PM.
And don't forget to thank and bump! We're trying to get to sticky status!
