Dear Category Theorists: This is a reminder, for those who wish to contribute to the special session on Mac Lane and Eilenberg at CT 2006, to send their abstracts by March 15. The special session will be chaired by Bill Lawvere. Due to popular demand, abstracts for the general sessions are also still being accepted until March 15. We would also like to remind people who are attending the conference to make their reservations with White Point as soon as possible as White Point is planning to release a part of our room block early next week. - The organizers, CT 2006 http://www.mathstat.dal.ca/~selinger/ct2006/
