When I was trying to initially register, I was unable to use "gmail" for my email address. I used my Hotmail account, but I would prefer to use my Gmail. After registering, I tried changing my email to my Gmail email account, but IPB said it was already taken. Could I have possibly registered here at some point in the distant past? I'm not sure. I do not remember if i did or not. I mean, I suppose I could have, but if I did, it would have been at least five or so years ago.
When I try changing my address in my profile, to my Gmail address, I receive this error: "That email address is already in use."
