Just warning the mods my girlfriend might register a DP account. She lives with me [basically], so this account that she registers will probably have the same IP address as my account (this one). I don't know though it may not...she's going to be on my laptop and I haven't logged into DP (I don't think) on my laptop. But because it's the same IP over wireless connection it may be same IP. This is okay right? Obviously we will not be exchanging iTrader etc or anything stupid of that manner. Giving a warning/heads up so I don't get my ass banned. Waiting for reply/confirmation.
Yes don't post in topic of each other and don't exchange I-trader and all thats nice your GF also join Enoy !!
I know there are some in the same position as you. Some are actual family members like sibling and or mother/daughter who share the same IP. I personally would not see this a problem as long as the mods/admin are aware of the two users/1 IP. And like seogoogle had said just mind your I-Traders and business that they do not tangle up or innerweave.
Just PM one of us when she sets up the account so we can mark it in the user notes. And you already seem to know, but of course avoid leaving iTrader, taking part in the same sales threads, bumping each others' threads, etc.... anything that would make it jump out as a dup account or abuse issue.
