Dear Participants to Diffraction 2010, this is the forth circular of the Workshop DIFFRACTION 2010: International Workshop on Diffraction in High-Energy Physics, to be held in Otranto (Lecce, Italy), September 10-15, 2010, web site http://www.cs.infn.it/diff2010. - Today is the last day for abstract submissions, so please hurry up to submit your talk, if you haven't done it yet, since from tomorrow we will start organizing the scientific program with the help of conveners. - A few points concerning the accommodation: * The Workshop venue is the hotel "Baia dei Turchi" in Otranto (www.baiadeiturchi.it, e-mail: info@baiadeiturchi.it); each participant must reserve the room himself within August 15; later reservations will be accepted only in case of room availability. * In case you meet any problem in making the reservation, please contact me or our Secretary, Rita Bertelli (e-mail: rita.bertelli@lnf.infn.it), and we will help you. * All rooms are double, but can be also used as single. However, since the number of room is limited, we encourage, especially the younger participants, to share the room. In case someone wants to share a room, but does not have a room-mate to indicate at the moment of the reservation, the hotel will anyhow accept the reservation; "pairings" in the rooms will be organized by us starting from August 15, according to some sensible criterion and after approval by the interested participants. * We realized that a few participants decided to reserve a room in other hotels. This is rather inconvenient for many reasons: there is no public transportation to the Workshop hotel and we will not organize daily transfers from other hotels; lunches and dinners in the Workshop hotel would not be included and should be paid separately. Part of the logistic problems would reflect also on us organizers, especially in relation with the social events and transfers from/to the airport. In addition to that, we believe that sharing also the spare time in a common location, is part of the scientific activity of a Workshop. For these reasons, we strongly recommend you not to take into consideration the possibility to reserve a room elsewhere. - As mentioned in the Web site, transfers from/to the airport of Brindisi (or the nearby City Terminal of Lecce) and the hotel Baia dei Turchi will be organized on Sept. 10 and on Sept. 15, while transfers in different dates should be organized by each participant privately. We ask you to send us at your earliest convenience, but not later than August 31, the arrival time in the airport of Brindisi and the number of your flight. Best regards, Alessandro Papa ############################################################### ADDRESS FOR CORRESPONDENCE TO LOCAL ORGANIZING COMMITTEE DIFFRACTION 2010 c/o Alessandro Papa Dipartimento di Fisica, Universita` della Calabria Ponte Bucci, cubo 31C I-87036 Arcavacata di Rende (Cosenza) Italy Phone: +39 0984 496015 (or 496018) Fax: +39 0984 494401 E-mail: diff2010@cs.infn.it For urgent communications after August 15, 2010 DIFFRACTION 2010 Alessandro Papa, phone: +39 320 8681201 Roberto Fiore, phone: +39 349 3230756
