Thanks!
I think the POB project has been abandoned by the creater that remains anonymous.
The discord channel is quiet and the domain for one of the front ends has expired.
I once started the #POBphotocontest to help promote the POB community. I received some big upvotes which I used as prize money.
I'm considering changing the title of the contest to the FriendlyMoose contest and maybe post it in a the photography community.
