1. Reach level 15 on razor. In order to receive credit, you must have a user account belonging to group lev15, and you must submit a write-up on how you broke each level. Include details (both narrative and code please). You are allowed to work in teams of at most two people. Teams need only have 1 member account at level 15, and only need to turn in one document.
2. Extra Credit
Don't do this unless you have already reached level 15 on razor and you want to do more.
Get to vortex12 on vortex. Refer to the vortex leveling guide to see how it works (it's quite different from razor). Same deal as above: you must document your work in order to receive credit. P.S. vortex is currently down so I won't be able to get the directions posted until it comes back.
