Dear Colleagues, As announced in Vancouver during the conference, a special issue of THEORY AND APPLICATIONS OF CATEGORIES devoted to the Conference Proceedings of CT2011 is planned. The guest editors are Marino Gran, George Janelidze, Stephen Lack, John MacDonald, and Walter Tholen. The deadline of submissions is November 30, 2011. All papers are to be sent as pdf files to George Janelidze (<george.janelidze@uct.ac.za> or <janelg@telkomsa.net>), with an indication of which Guest Editor you prefer to handle your submission. As always, according to CT Conference traditions, the papers submitted must meet the high standards of the journal, but need not be precisely restricted to the talks of the conference. Looking forward to receiving your good papers- Marino, George, Steve, John, Walter [For admin and other information see: http://www.mta.ca/~cat-dist/ ]
