It seems I can’t remember if at one point I had 2 wordpress blogs– I received an email saying that I had to change my email because someone else was using it. That is not the case because the email addy is my personal one and registered. Can you share how this might happen and share what blog is using this other email? here is my site trumpeter.wordpress.com
The forums are staffed by volunteers, so it can take us a little while to answer questions. Can you explain what’s happened a little more clearly? I’m not sure what you mean… you got an email from WordPress asking you to change your email? I’ve never heard of that, not without requesting the change in your profile.
