So far the site is just a quick one-page overview - we haven't had a chance to flesh out any of the detail yet at all; sorry about that :) To answer the questions: * 1:1 VoIP is supported on WebRTC on the web version, Android, and iOS coming very shortly. On Web you hit the call buttons on the bottom right; on Android it's currently hidden behind the top-left menu. * Multiway VoIP is very beta, but supported on the web version. Hit the call buttons when in a room. * Screensharing is even more beta, but happens to be there as an undocumented easter egg on Web. Currently it only works if you're running on Chrome with the --enable-usermedia-screen-capturing commandline option, and shift-click on the video call button. Obviously this isn't intended remotely for serious use yet, but we're working on it. * The three platforms supported are Web/iOS/Android. You can of course run the Web client fine on Windows/OSX/Linux. If you want a different native client, go experiment with the other options on http://matrix.org/docs/projects/try-matrix-now.html http://matrix.org/docs/projects/try-matrix-now.html * The page you failed to find for the Synapse server is probably the read me at https://github.com/matrix-org/synapse https://github.com/matrix-org/synapse. Agreed we need to make this clearer, and provide much better simple overviews and tutorials for getting up and running. * Agreed that Slack have amazing documentation - it's something we desperately need to do better at. I'd like to think our "customer support" isn't too bad, though; good luck in getting one of Slack's co-founders answering your feedback on HN ;D
