A: 1 - When sharing computer screen in a meeting there is no way to share the (system) audio, like in all other tools. So showing my VA part of a video etc. is not possible, so we still use another video tool.

In the meeting room yyou cna select in settings the source of audio, maybe i undertand your issue if you can share me more info into support@edworking.com i can check better with my team

2 - There is no way to select the webcam when making a story. I have a few webcams connected, including some 'virtual' webcams like Chromacam or Manycam. The system just picks a webcam, but you cannot change that, so in my case it is a black screen. So the only stories I can make is with with screen sharing.

Yes this is a improvment at the moment storyes is not selectable the source of video, will be in the next months

3 - Signing up a new team member is very confusing to me. It is not like I am used to in other tools that you add a new team member and that he/she is invited by email and can sign up. Apparently the new team member first have to make an account. Or, am I doing something wrong here?

you can invite people via email for sure, or via link and they will receive a email, let me know if you want a on boarding session

thanks
