To move contacts from the Address Book select Export..., from Address Book's File menu and then, Address Book Archive. Give the archive a name and save it. If the other user account is on the same computer/network you can drag the saved archive into the User's Drop Box in their Public folder, otherwise email it if it is not too large. The recipient can then select Import... from the new Address Book.
you do something
you can set up another account or a different computer, OR change your IP address
The exact same way you made the first. You just have to use a different email address.
another email address
You would need to keep the account you have the now and make another one but with a different email address.
Perhaps you registered another account in the past with that address, then forgot. Or someone else in your family, if you share an email address. Just use a different email address; it is fairly easy (and free) to get more than one email address.
Open Gmail Click on your profile picture at the top left of the screen Click on Add another account Choose the type of account you want to add
make another with a different name, but you will have to have another email to go with the new account.
You cannot.
It is as long as your email address is still valid when you create another account.
Only if you changed the email address to something else on the deleted account before deleting it. Otherwise, no. You will need a new email address.
You can't unban yourself! To play just make an another account using a different email address from the original one.
