Well, although we don't like it, Outsider is all for it and it's his site. With that said, here are some guidelines to follow for game sharing:
1.) Try to trade with respected or trusted members.
2.) Use some sort of defense such as security questions or a second email in case you need to recover your account.
3.) We do not enforce over game sharing, so therefore if you get your account scammed, sorry buy you are SOL. At most we may ban the person, but say goodbye to your account.
Thank you NP Carling26 for the quidelines. For my own security I will be setting up a "Dummy" account for these transactions. In order for me to know who is interested in Map Pack sharing you must send me a private IM introducing yourself and setting this up with me. I look forward to assisting the NGU community.
