The Cities Zone had the highest number of registered students for all the zones, which kept the site lively and busy. The live chats were great with a lot of really engaged classes, and questions focused on engineering’s contribution to the future of buildings, cities and energy. All the engineers in the zone were really engaged, sharing the load of questions answering and chatting in the ASK and CHAT sections between all 5 of them, as well as lots of discussion on Twitter. They were so even that there was a tie on the first eviction day!
