How can I edit my name in yahoo?

How can I edit the contents of a group in Yahoo Mail (other than sort by 1st name, etc.) I want to be able to?

• How do you add/delete members of an address list ?

• Answer:

  Yahoo seems to have changed the method of email list editing (like in the last few months), agggghhhhhhhh!!!! Before you would click on the email list (ie, category) of interest, and then two columns appear, the left column contained a list of all your Yahoo email contacts (ie., in your address book) and the right column contained the email addresses of the previously selected contacts on the list. To add or deletes a contact, highlight it then move it onto to the list or off the list. NOW, it is incomprehensible how do simply to this. At best it seems that you need to enter each contact and then add or remove the name to the category. Great, this probably takes 30 times as long to do. WHAT IS YAHOO THINKING, it has gone from good to ridiculous. So, in short, I am searching for the old simple way, and still have not found it (short of entering and exiting each contact to add/delete from a category).
