How can i delete all my yahoo inbox messages?

I want to empty my yahoo inbox,can anybody guide to achieve it?|||in your inbox u will find a box in front of all messages; tick all of them and click the delete button or u can go to the option 'more actions' and then click select all messages and then press delete button. U can also find all messages in in trash so if u want 2 delete frm there also then do the same in trash.
