guys i share my account with three people, but we are on the same ISP and we download at home + at uni (same uni all 4 of us).
so the number of IPs is 3.
it happened twice that they warned us by reseting the password, but now we are more careful about the IP issue.
and btw, speaking of traffic and sharing, use up some rs points, this will expand the quota, my account can cumulate to 25gb
