Dear Colleagues The loss of Marek comes as a real shock to me. I emailed him recently asking whether he would referee a paper. He told me he was undergoing treatment but could begin a report after June. I said I would ask other people and, if I had no suitable report by June, I would take up his offer. He confirmed that he was happy with that on 27 February. I agree with all the comments about Marek's pleasant nature and I respect his great contribution to mathematics. Please if you can, Ryszard, convey my sincere condolences to Marek's family.
