You also knew that you weren't quite done with them.
They first appeared in Week 20. They menaced you again in Week 25. You may have thought you were safe, until you had to do two of them for Week 32!!
That's only four of them accounted for though - and there are 6 topics. :)
So now you need to select another one that you have not yet completed:
Intersubjectivity, Shibusa, Rapture of the Deep, Captcha the Flag, the Bystander Effect, Overwatch
You have until Thursday Feb 12th at 8pm EST to link your entry back to this thread. (and let me know which one you have selected!)
