I created the Shotcut - Free Video Editor Facebook group.
I don’t spend much time at all on FB but can’t hurt to try to grab some attention/centralize support there.
Developers and moderators are welcome to become group mods/admins (expected workload: accepting new users whenever you happen to be online once a week or month 
)
There is already a big group but it has a suspicious link right in the description.
It’s good to have it, yeah. FB pages are like web blogs and FB groups are like web forums - creator-centered vs. community-centered. So hopefully the group will serve some people.
You may reach out to the facebook developer’s portal in case of further clarfifications
You can find more to-the-point solutions for anything and everything
This Facebook group is not attended by any members of the Shotcut team, nor will it likely ever be.
