How much chars to one IP ? xP
:D Just for Info x)
1+1 (not 100% confirmed, but staff are closer to chosing this option).
PS: This rule apply for every PC which is by the rule played by one player. That means if more than one player plays from the same IP, each and every player will be able to use 1+1 box. However, there is still remaining issue of one player using several computers.
