EDIT: Folders should now all be open for submissions again, and Join requests back to auto-approval. Leave a comment below if you find something that still isn't working properly.
I reset group permissions, because the group couldn't be joined, but I don't have rights to set anything for members, so now everywhere are group defaults. So....you cannot submit your art to folders, except for Featured. I think we can use that for now.
I wrote a note to the group founder XaelMcEwan and I hope we will sort this out soon.
P.S. you can join the group now
