Using unused Google Apps accounts

In fact, the topic claims to be the captain, but I would venture to write it, because I did not know that there was such an opportunity, and I was in despair for a couple of days.
As we know, recently google has disabled registration of Google Apps Free for new users, leaving the opportunity to use the service for domains that have already been registered.
At first this news saddened me, and I tried to look for alternatives, but it became clear that they were not there, except for Yandex, which at one time did not accept the quality of the mail and the lack of such tight integration with the smartphone. The cost of service from google for personal amateur projects is high. But the solution was found!

It turned out that several personal domains can be linked to one account.
I think not one, I tried to do various services, and simultaneously registered for myself Google Apps Free. Rummaging in my memory and zagashniki I found these 4 pieces.
We remember the password and login to log in as a super-administrator, and further:
Domain Settings - Domain Names - Add a domain or domain alias.
Add a new domain, make a user for it, if you wish, we can designate it as a superuser.
Thus, it is possible to extend the freebies a little more, in my case these are additional 4 dozen addresses.
I hope this information will help desperate.
ps I want to believe that with the departure of Google from this market, someone will take their place with the same excellent antispam, jabber and other buns, but at an affordable price.

ps 2: I wonder if there will be a market for bashy (poyuzanny) apps free? :) In my opinion for an adequate price, such things can be offered for sale.
