  And I take this opportunity to proanonsirovat pleasant news for us: we are going to publish an electronic version of the book "fascinating experience for the children." Nesting is already in the middle distance, almost all video captured. But we were asked to publish a printed book, and try to raise funds for its printing platform through kraudfandingovuyu Boomstarter.ru .

Only registered users can participate in the survey. Sign , please. Voted 688 people. Abstain 278 people.
