Just noticed a neat new little security feature that popped up in Gmail. Down at the very bottom of your mail screen you'll now find a line that says "Last account activity: 0 minutes ago at IP xx.xxx.xxx.xxx." Click that link and you'll get all the details on from what IP address your account and for how long your account has been accessed, so you can keep track of any funny business. But perhaps even more useful for those of us not involved in messy domestic spying situations, there's also a one-click button that remotely signs you out of every Gmail acccount other than the one you current have open. No more running back to your work desk to make sure you logged off and the cleaning crew's not reading your email.
