How do I delete a list/category on my address book?

• I have a list of contacts in a category on my address book which i do not use . How do I erase the list from my address book?

• Answer:

  From the main mail screen, click on the Addresses tab near the top left. Pick the list with the names you want to delete and scroll to the bottom. There's a Check All link you can use to select all of the listed contacts, and then you can click Delete to get rid of them all. You can delete unused categories by clicking on Edit next to Categories on the left of your screen, and then clicking on Delete next to the one you want to get rid of.
