Dang kittens have started playing at the computer every time I turn my back.
If you see any out-of-character blog posts or comments, or receive any e-mails from me (possibly by way of a list) that look like someone walked across the keyboard... blame Unauthorized Furry Personnel.
I suppose a cardboard cover (or just inverting the keyboard) will work for a little while. Gonna need something sturdy and/or anchored soon, though.
Update: actually, just adding the lock/logout widget to the panel, and remembering to click "lock" when I leave, should do the trick.
