Telenor has made a video conferencing service called appear.in (Twitter: @appear_in) – and it is fantastic! All you need to do is open a browser window and type
where “something” is a word you choose. The other participants do the same, and you are in conference. Camera, screen sharing, everything work great, the whole thing is free (at least with up to four participants, have not tested with more). If you want your own room with your own design there is a premium version for $12 per month. No app installation, no weird settings, no drivers, no updates. Just works. Excellent!
(No, I am not sponsored. Just like the service.)
