Greetings, and welcome to the fourth issue of the ISOO newsletter. Firstly thank Gyou to everyone who has already submitted abstracts and registered for the Cleveland meeting. I know some of you have experienced difficulties with abstract submission. Please accept our sincere apologies. Our Website Editor and Treasurer, Dr Shahar Frenkel, has now improved the website to faciliate the process. The abstract submission deadline has now been extended to Sunday 16th June for everyone who had paid their membership dues by the Saturday 8th June, 2013.
