from Nicholas Tutunina, a representative of the company OnWebinar:
The platform is free, however to visit some webinars need to register. The possibility to download the recordings of the webinars (and recording them) yet, but will be available after 15 Feb (function in development). Users can completely free to create and give your own webinars (open, closed(password access) and paid), you need to register and install the client. There are surcharge rates, apply to the licensing of the technology, getting access to the API and other functions. The service has everything you need: stream video, General and personal chat, sharing resources (the Board drawing, presentations, files and links), surveys and video conferencing. A demonstration desktop as well as the recording of webinars will be available after February 15.
The solution is built on технологиир2р.
