Hi StephaniePT, if you make a little search in the forum surely that you can find good explanations for doing what you wish, in particular I have found two entrances that seem quite satisfactory:

Hope this help,

Actually neither of those were what I wanted (and the second is not confirmed to work with Technorati), but I got it figured out. :) I knew I was just thinking about it too hard!

StephaniePT sounds like you want to modify the skin? And if you figured it out, post what you found so anyone else trying to do the same knows the answer! ;) :)
