Project 1999 - Question, sorry if already answered elsewhere

Hi. I recently started playing on this server and am in love with it. I'm trying to talk my roommate into giving it a try, since it's such an accurate recreation of classic EQ.

Who do I need to talk to and what proofs of the fact that there really are two of us instead of one person two-boxing to get permission for the two simultaneous connections from one IP?

This is a little premature, as he hasn't installed yet, but I feel the probability approaches 1 that he'll be playing within the week.

Thank you for your replies in advance.
