Hi, I'm interested in building a website where users can sign up, edit their profile and have a friends list where they can send and receive private IMs. Also there's a more intricate part that I need. users need to be able to host lobbies where they can invite other users and talk via mic. Lobbies have to be able to be password protected and the site has to be able to host hundreds, possibly thousands of users on at the same time. I'm wondering what this would cost and what I would need to do to get this started. Any and all information is appreciated and if you have any questions let me know and I will answer as soon as possible.
