I apologize if this was answered already.  Are there going to be anymore Skillz challenges this year?  I really like the Prison Break challenge.  There has been a lot of security topics for the year that may be cool to include:

-Mobile Phone Security
-Adobe (of course)
-Social Engineering

I guess it would be hard to include them in a challenge I suppose.  But it is something to work with. 

Thanks COm_BOY.  I took a look and went through some of the challenges.  I do like some of the programming ones and the Exploit challenge.  As far as the quality, it was a complete range of 1 - 10.  Some challenges were just looking through Google and some had you test your Assembly/Debugging skills.  It is definitely worth a quick look. I have been trying to look for as many challenges as possible to prepare for the OSCP course.  If anyone else is looking, here are some I have seen:
