I've posted the solution to Problem #4. In addition to the link from here, you'll find links on the detail page of the lecture for the 14th of April, when it was due, and from the "Notes" page. In fact, I've collected notes for all WinBUGS related problems at the bottom of the notes page, so it will be easy for you to find them if you ever want to refresh your memory.
I hope to have some notes posted on evolution in multigene families late tonight or early tomorrow morning, but there's a good chance we won't start talking about that until Monday anyway. So don't worry if they're not there (as if you would anyway).
