This is not a MultiID that I been review and give to you before. If Multi ID have to change your register of yahoo messenger, Public ID are deferential of your main (primary) ID and do not have to change your yahoo messenger. Multi ID don’t have a limitation, but Public ID have a limitation. The limit of Public ID is 6 six ID.
With Public Id or Alias ID , you will be able to chat with your friend with 7 Id (including primary ID. You can join to room with one of your Public ID but you will never join room with 2 or more Public ID. This is not like Multi ID that can be joined to chat room with 2 or more ID. Public ID can be activated or deactivated depending of your self.
With Public ID you will be able to join to yahoo messenger with one of your Public ID. This mean that you will be able to join to yahoo messenger not only with your primary ID, but also with all of your Public ID can be used to join to yahoo messenger. Of course, your password of all your Public ID has the same to your Primary ID.
You can have a fun thing with using Public ID such as: changing Id frequently when your join chat room, chat with your friend with an ID that not knowing, disguise yourself if you met your friend in chat room and other.
Public ID cannot be used to login to yahoo mail. You must use your primary Id which have a same address with your yahoo mail to login to yahoo mail. You can create Public ID trough this step.
Open your browser and type this link: http://profiles.yahoo.com/username. If you are not logged to yahoo, you must login first to make that link appears.
