• Answer:

  EDITING CONTACTS To edit the information for ONE of your contacts click on CONTACTS...once your list is showing click on the NAME only (do not place a check mark in the box to the left of the name) and this will bring up the EDIT option... Click on CONTACTS on your email page. Once your list comes up you can place a check mark in the box to the left of it and that will bring up ..SEND EMAIL....INVITE TO CONNECT....ADD TO CATEGORY....DELETE....... If you want to delete more than one at a time just place a check mark in the box to the left of SORTED and this will place a checkmark in front of ALL of your contacts. You then have to go down your list and click on each check mark that you DO NOT want deleted and this will remove the check mark. You then can pick the option for the remaining contacts..... NOTE: Please remember to pick the best answer by clicking on the THUMBS UP at the end of the answer you choose...thanx
