First I knew were alerts to confirm my new email address and password - neither of which I had changed. Needless to say I was then locked out of my account! The hacker had used my account to email several other members about expensive laptops etc. I am told that this has all been sorted out and I have finally got my account back (with new password etc.) and have had to change settings on my email.
Very annoying!
It might be worth checking your account for strange alerts...
