The "good" news outweigh the bad: >2000 students/faculty from Saint-Petersburg University sign the anti-war petition (despite this act now bing punishable). This outweighs the letter of 600 produced in support of the war (with all the admin encouragement).

I miss having World Congress of Econometrics Society in Milan 2020: hunting for the next good session, meeting people you've never met before, chatting, and having drinks with friends. It seems impossible to replicate the live experience via Zoom, esp. big conferences. Any +s?

@phl43 Philippe, I wanted to thank you very much for your critique. Hiro, Paul, and I are taking a deep dive and will provide a detailed response in a format of a paper. The estimated amount of work is at least one month.

I teach 14.382 (Econometrics I) using chalk and blackboard. I have to teach again in the spring via Zoom (most likely), and would like to do avoid using slides. Any recommendations would be helpful.

I didn't have a chance to contribute to wording (no option was given), but was happy to sign it. I would like to see the return of election at town and city levels, competitive parliamentary and presidential elections. Election are our true Russian tradition (Novgorod & South).
