I was wanting to do a WiC style collab group for my new theme ,Cyberspace,here
on Bricklink, without having to start that group on another platform such as
Flickr or Instagram. Maybe there could be a new feature on the gallery where
you could make groups with other designers to work on a common theme or interest.
The groups could have their own coordinators or mini-admin to accept designers
into the group and make sure all builds are of good quality. It would really
make the gallery more interesting, and could go on to be the roots of new community.
