Check if your online accounts have been compromised.

Via Krebsonsecurity, a site (PwnedList) that you can use to see if your email addy has been compromised by hackers, checking it against compiled public lists from torrent and pastbin sites.

Use your email addy, not your username, because you may come across other folks who seemingly use the same username, but were compromised.

Of course, if you have Gmail, it's not that hard to check activity on your account.  In Gmail, in the bottom right hand corner, you can click thru to check the activity on your account.  When you click thru, it'll show the IP addresses from which your Gmail was accessed from.

Don't fret if you get addresses from locations that aren't geographically correct, because those IP traces are to your ISP's servers -- in my case, Clearwire has servers located in Idaho.

In that window showing the list of IP that were used to access your Gmail, at the bottom of the page you can set up an alarm for any suspicious activity.
