Well they promised the 2 box limit will be lifted after a while, let's see if they will keep their word
I know about that pretty well.
At first they said about 2 box limit because of hardware limitations and 6 hours later you can see that they have a whole scheme set up with Premium Accounts and extra window payments.
The whole problem is that an extra window costs 90 RUR. But I am sure that it will be 90 per month.
