Having more than one account is against the rules. When I find that you have more than one account, I can and will shut both the new account AND your primary account, even if it is long-established. There is a little stunt recently of long-term posters signing up new accounts so that they can either support their primary account during an argument, or else make trouble (attack others) with the new account. I would suggest that if you have more than one account, you get hold of me and tell me which one to shut, before I get to it and shut all of your accounts. I have already shut some dual accounts (and their primary accounts) and won't hesitate to shut more.
