Thank you but yes I'm sure. I wasn't offline but standing next to him when he complained he couldn't send me something ingame, a photo I presumed. He suggested he could send it by email. I had no desire for that and didn't respond back. Several few minutes later in a "freindly" conversation he complained that I wasn't taking his email. I thought nothing of it since I hadn't given out my email address and never would. Today I see the two messages in my email inbox and the sender is shown as dsktop and the second is from dkstop2.
Also my dashboard settings have always been to receive NO emails of my offline IMs or anything else from Second Life. So, I'm puzzled here.
