Starting to flesh out the blogroll a little, dabbled briefly with dividing it into categories. I quickly returned to a single list upon realising that friends who are librarians would appear twice. The wordpress.com version of wordpress insists on capitalising each word in the blogroll too. I prefer all lowercase myself for headings as do some of the blogs I link to. Probably yet another reason to move over to my own server with my own wordpress install as I’ve noticed a friend has, though she was moving from blogger.

woo! back on the blogroll.
if you can get to the stylesheet within the template, you could force it to lowercase with the old
text-transform: lowercase;
I can get to it, but it costs to save changes. I don’t think it’s very expensive but the cost is annual for CSS changes.
maybe you can embed an extra stylesheet as part of the link or the link text?
