For all of you who are using labels when posting to your blogs: Be sure to add the gadget to your page. This will display a list of all the labels you have entered and allows everything under each category to be accessible simply by clicking the links that the gadget creates. Here is how to do it:
-After logging in, in the right top corner of your screen click customize,
-Click "add a gadget" from the list of page elements displayed(it will be at the top),
-scroll down until you get to the gadget that says "labels" and click the [+] button.
From here it is self explanatory. Then when you view your blog, this feature will appear with your profile, and archives. You will only have to do this once, and any subsequent label you employ will automatically be added to this list.
