How to delete a category in WP blog?

Hi guys,
I want to delete a category that I added some time back in my blog. How do I do that? Could someone help me out?

Thanks in advance.

 

yourblog.com/wp-admin >> Manage >> Categories --- This is the place where you can play with your categories.

Actual address - Yourblog.com/wp-admin/categories.php

 

If its the default category I think you need to choose a different category as the default before you can delete it.
