Some questions about Blab

iOS and iPadOS

Is there a way on Blab to start with a completely "new" or "blank" conference and invite followers from there?

Also, is there a way to invite people in, say, from Twitter and/or Facebook who might not already have Blab or a Blab account? Is there a way to invite participants from Twitter/Facebook at all?

Further, is there a way to find friends you already follow from Facebook/Twitter and add them to your Blab contacts via the Blab app?

Finally, how accessible is the app, really? (Someone needs to do an official review here.)
