I noticed with the new upgrade that Hotmail did to the OUTLOOK system, that now, when a gent (or female) sends me an email---if they have a Facebook page or maybe it's from the MSN Messenger profile (not sure on that), the photo on their Facebook page shows up as an icon/avatar next to the incoming email when I'm reading the message.
Not sure if you folks who don't want your face shown in your emails, know about this. I think it's rude of MSN to merge Facebook stuff like that. I don't know if its something you can turn on or off in Outlook or if it's something that needs to be done in Facebook, but I wanted to make you folks aware because so far, I told 1 gent (who's son's photo came up in the email) and he was "not" aware of that.
