Hmmm. I couldn't find where to remove it. The website field is blank and there is no field for "blog". However, when I look at the "My Account" page, the link for "blog" still shows up. the link is as follows:
http://www.breakradioshow.com/archives/ ... -rob-behr/
That was entered before your site migration/update, so the blog link may be stranded in place. On the old system, I think there was a specific "blog" field for a URL. If it can't be removed, it's not the end of the world.
Thanks!
