Using my iPad got into the Demo, problem Part of the language is English, and other parts Russian.
I can not recommend this software to a company when the Demo is in 2 languages.
Demo killed prospect. Epic failure.

Doing a demo on a public server where anybody can enter anything is a very bold move.
Would not recommend.
Also it is probably because someone has changed the language of the demo user from English to Russian. This can happen on a shared demo server.
