Updated summer school information

We try to schedule our Qatar regulation tours in middle of the European winter

It is minus eleven outside as I type this (minus twenty-three in Moscow!), so it's nice to think ahead to 2012's summer schools, whose websites are now mostly updated for this year. On Harpblog's opportunities page, you will now find links to the summer academies with, among others, Isabelle Moretti, Germaine Lorenzini and Isabelle Perrin. I'll be adding to this list throughout the long, cold winter.
