I have spent way too much time over the last two days trying to change the theme templates on two categories. I ended up changing two categories since I think I have a more severe problem with one category. It hasn't updated since 8 October. I found some nice resources that imply that this should all work but I haven't quite figured out when things get updated.
Along the way I figured out how to add and modify my blogroll. Some of the stuff is cool. Some of the stuff took way too much work!
