TCS+ is a biweekly online seminar series in theoretical computer science, accessible to the widest possible audience, and ensuring a carbon-free dissemination of ideas across the globe. Full details are available on the website: https://sites.google.com/site/plustcs/.
Any individual can sign up on behalf of a group for a slot in the Hangout here: https://sites.google.com/site/plustcs/livetalk. One should sign up for a slot, reserve a room in Stata for viewing, publicize this to the theory group, and set up their computer for joining the Hangout and watching to talk. If there are no more slots available, you can still watch live via Youtube, with a link available at the same URL.
