my nephew is going to be getting internet on his computer in a day or two and I was reading the rules on talking to family members on here and found this

Do note that without proof of identity, multiple users on the same IP address will not be allowed to converse with one another within the site.

Once identity has been proven, however, you're free to converse freely with your friends, siblings and whomever else may be on your IP address.

so I was wondering how do we prove that we are not the same person or what ever needs to be done?

Multiple accounts on the same IP
Because a number of users have family members/room mates who also belong to Menewsha, and access it via the same computer, we often end up with a number of accounts using the same IP. If this is the case in your household or dorm, we ask you to contact a staff member and let us know who everyone is to avoid future confusion.
Please be aware though, we may ask for proof that the accounts do belong to seperate people, and we will check regularly for suspicious activity between them.
The ruling that 2 accounts on the same IP cannot converse together applies here also, regardless of whether the account belongs to someone else.

Quoted from Jellysundae in THIS thread. That thread has more information you can read up on, but if your nephew doesn't live with you you're fine.

As long as there's no suspicious trading or gold donations between the 2 accounts, there'll be no problem.

I doubt very much that your nephew will "sound" like you when he posts either.

The main reason we were forced to bring in this ruling was because of people inventing siblings to roleplay with, then we'd check the cash logs and find all the money being sent over to the main account..

:O!! Jelly double posted! *banhammer*
...XD
I know, I know, it was a glitch.
