I just got an email that looked identical to the AHA Forum new topic notification emails. It contained the normal links, but they were to bogus versions of the website. I'm sure the goal is try get you to try to log in on the bogus site, at which point they can log in here and post spam.
The message was completely off topic, which should help you recognize it - Selecting a hairstyle for a wedding. But the look is identical.
I'd be happy to forward the message to AHA IT if they want to see it. Just send me an address.
And no I didn't compromise my account.
Also, I realize this is probably a 'Forum Admin' thread, but I thought more would see the warning here. Feel free to move this and smack my hands.
