For the past several years, IDG World Expo has created a community on Ning for Macworld Expo. You can join up and follow various bloggers and companies, and now TUAW has a group page for the show.
To join the group, just head over to http://macworldexpo.ning.com/group/tuaw. You can participate in our Macworld Expo discussion, find out where TUAW bloggers will be at the show, and even find out about possible meetups in San Francisco during Macworld.
It's all free, and we'd love to have you join in on the fun. If you already have a login for the Macworld 2010 site, simply ask to be added to the group. For those who don't have a login, you can sign up by clicking the appropriate Sign Up link on the right side of the page.
