How can I change my email address with one of my Aliases?

• my email address an real ID is ex: [email protected] . but I connect to yahoo messenger with one of my Aliases & no one know my real ID. now,i want to change one of my aliases with my real ID, if any one send a mail to me,use the aliases address ex: [email protected]. but I can't create a new ID & email address,because I have a lot of id that added in the primary. **I want that no one understand that I change my ID & see me as the one aliases that i want to change with the primary ID**

• Answer:

  You are allowed one main ID and one alias email address. Along with those you can have unlimited IDs for chatting. The main ID can't be exchanged with the alias or the other IDs. The alias email address can't be exchanged with the other IDs. The alias email address goes to the same mailbox as the main address. You can sign in with the alias email address and I think you can sign in with the unlimited chatting IDs but you are still in the same account. ₪ ʎəɿʞɹɐq ₪
