slpgal123, is this old email address listed on your Facebook account or other social media that is under your real name. We should consider that just like employers looking at potential hires, perhaps the adcoms look at our facebook accounts to see what sort of person we are....(?!!!). Which is a good reminder to keep anything we wouldn't want people outside our peer group to see, as private. I don't want to kick off a wave of paranoia, but it's something to consider.
Anyhow, perhaps this is where your alternative email address was found. Just a thought...
