When I am on a wordpress site and clearly logged in as me (in the top right hand corner), and try to comment on someone else's blog, I always get taken to a new page. That page tells me I am trying to post a comment under an email address that I no longer use, and haven't used for a long time. It tries to force me to enter the password that must have been associated with that account a long time ago. It also doesn't allow me to log in under the email address I am actually using. The page just refreshes with an error message asking me to give the password for the old account. I have no problems posting comments in Reader, (so have had to follow my own blog to reply to comments there), but this happens when I am in the blog site proper. I have some screenshots of this, but can't see a way to upload them.
The blog I need help with is mypurseisclosed.wordpress.com.
