Dear colleagues, Given the very sad news of last week, it seems to us sensible to extend the deadline for the submission of papers to the TAC special volume dedicated to the work of Marta Bunge. As a friend noted, several people (himself included), who would like to contribute, felt that the deadline was too close, they were too busy with the new academic year post-pandemic. A new firm deadline of 31st March might make sure that everyone who wants to honor Marta has a chance. As mentioned before, no one knew Marta would become ill when we started this project: we meant it purely from the perspective of celebrating her work. But now everyone feels an extra poignancy, a need to say thank you for all she has done. It would be good to honor that need too. Perhaps we can collect some personal histories. For example, Micah McCurdy on Twitter wrote: "I hardly knew her at all but one time when I was very young at the Carvoeiro CT there was another young attendee who had some sort of panic attack and she was immensely kind to him, missed a talk to calm him down. RIP." We're sure there are other stories. The new deadline and any other information we think might be useful will be on the webpage https://sites.google.com/view/marta-bunge-festschrift/home. Please let us know if you have any questions or suggestions.
