[change] SIGCHI elections

Hi Everyone, The SIGCHI elections are coming up, and you have to be a SIGCHI member on March 15 to vote. If you're not already a SIGCHI member, you can sign up here: https://www.acm.org/special-interest-groups/sigs/sigchi. (Apparently, you don't have to be an ACM member to be a SIGCHI member.) The SIGCHI membership pays for itself through the discount you get for registration to CHI and other SIGCHI-sponsored conferences. One reason I'm sending this out is that Neha Kumar <https://www.nehakumar.org/> and Shaowen Bardzell <https://shaowenbardzell.com/about/> are on the ballot for President/Exec VP, and I think they would be terrific for moving the SIGCHI community toward greater inclusiveness. Thanks! Kentaro
