In some cases more than one person wishes to play AVH from the same home and since the rules specify there should be only one account per IP, a new feature was added.
If more than one person is playing from the same home you can now register their login as a secondary one.
This way we will know that you do not intend to break the rules.
Once you do this you will not be allowed to partner the account of your relative/friend but you will not have to wonder whether you will be banned/blocked from the game.
You can find this option on the I want to menu under Game Settings >> Other logins

Note: This does NOT mean that anyone can just create multiple accounts and pretend that there are more people playing the game. It is simply a way to give some peace of mind to people who actually play from the same location.
