Dear Category Theorists, I am glad to announce the creation of a new blog and forum about toposes: http://www.aroundtoposes.com This provides a platform for discussing about any aspect of toposes, at different levels of knowledge and technical sophistication, as well as a space where people interested in learning the subject can meet and set up reading groups. Anyone with these interests is welcome to join our forum. We look forward to seeing many of you there! Olivia [For admin and other information see: http://www.mta.ca/~cat-dist/ ]
