Heads-up to my email contacts

This morning I logged into my Yahoo! account to see 45 autoreplies and failure notices...for emails I hadn't sent.

Yes, I've been hacked. I think I recognize the particular method of hacking, as I've been receiving those spam email messages (titled, as it happens "message" in the subject bar) for a week or so now from another friend's account. I thought I'd taken care to avoid clicking anything inside them, but, well. I've changed my password and tightened account security, which I hope will be enough to clean the problem up. In the meantime, I apologize, and please, please do not click any links "I" send you!
