peahen on "My Comment - changing the blog link"

I have two blogs in wordpress.com. My original one is http://nestless.wordpress.com. After a while I turned this blog from public to private and opened another blog http://tweedleanddoodle.wordpress.com. This one is public. Now I am running into a problem when I comment in other blogs.
My comments in other wordpress blogs shows my user name as a link, and when people click on that they are taken to a subscription page for my private and original blog. How can I change this so that link takes them to my public blog? I did try to change this through settings, but nothing has changed.
Thank you for helping!
