Is a "log out from every SE site in the network" button technically feasible?
With so many SE sites popping up, it would be a very useful feature.
Edit: has this been implemented now, as @Ben suggests in his comment? I've lost track.
Yes, please implement this
I often like to check SE sites while not at home, and I don't like leaving myself logged in on someone else's computer. Currently I have to go to each site individually and log out. If I miss any site, then they get logged in as me if they go to any SE site afterwards.
As for the current suggestion of clearing cookies/temp data, it doesn't seem right to clear someone else's cookies and temp data, so its not a solution I ever use.
