Add “network wide logout” functionality
I've tried it on different Stack Exchange sites. There are individual sessions maintained for each site. Logging in/out on one site doesn't reflect on the other. I have to manually log in/out on the other. It would be better to have single login/logout. Because it's hard to remember all the sites that I've logged in especially when at work. Or is it already available in Stack Exchange, and I didn't notice?
I tried logging out from stackoverflow.com but I'm still logged in in meta.stackoverflow.com. Do I have to change any setting to log out all the sessions?
