The link above is from 2015 with seemingly no recent updates. It didn't even receive an update after the Firefox transition to quantum.
I will need to use Ether-Pad with other users simultaneously for my new job and am hoping someone has experience more recent than 2015. It would be especially useful since the documentation doesn't seem to address writing live with collaborators at all. The little experience I've had so far suggests that NVDA does not get any information about others writing in the document since I got absolutely no feedback while my boss edited the agenda we were working on.
Please feel free to reply off-list if you can help.
