I'm trying to get my roommate to join, but I noticed in the account section that IP address are logged and you can only have one account.. I want to make sure that I'm not mistaken for her or vis versa.

Other sites that we are on there is a place to post shared IP's for this purpose.

Thank you!

Thanks for suggestion. Shared IPs topic is created here.

P.S. We're not going to organize a witch-hunt after players who use the same IPs. Except the case with roommates, family members and friends, there's a situation when internet provider gives "gray" IPs to all users of the network and all off them will have the same IP. We can't ban people only because they don't have their own IP :)  But the abusive multiaccounting (like creating 10+ accounts with benefit for only one) will definitely attract attention.

Thank you! :) Good to know!
