I wanted to move two problems from double snapback to snapback workshop. It's been rather awkward to do this and preserve the idea of having easy problems at the beginning. The first one was a fairly tough problem. So it's been added at the end, as problem #41. However, the other problem is a simple problem so I wanted it near the beginning of the snapback workshop. I arbitrarily put it here, and added links to it in the snapback workshop page. However, in the text links section it didn't display right.

In the end I managed editing snapback workshop as follows. I inserted it as "problem 3b", and renaming "problem 3" to "problem 3a". Phew... Go is easy compared to SL...
