Message of the Day

Today's "Message of the Day", the message that appears when the game is loading was interesting.

Linden Lab will never ask your for your Second Life Password --keep you account secure, don't share your Password with anyone!

Grammar errors are Linden Lab's. It looks like it was quickly put up. What is the reason for this? Was someone's account broken into? I have heard tales of that on the forums, but never thought it might actually happen. Should I change my password? What do I do? Help!
