Just thought I would pass this along in case it helps.
I created a link category called friends, and had the original "blogroll" category. I wanted to make "friends" my default category, so first I deleted my friends category (which had 7 links) expecting the links to go to the blogroll category, which I would then rename.
However, the links were deleted when I deleted the category. Now, I cannot change the blogroll name to "friends." I can change it to anything else I want (I've tried "Friends2", and "Google"), but not friends.
Not sure what's wrong?
