You know, it may be time to go mobile with this. Figuratively and literally.
I see plenty of PJ posters using Instagram. Maybe you guys should come up with an official hashtag for folks who are active, but don't post here due to how interacting with the internet is changing?
Pick a hashtag, post it with each topic so it stays in minds, and folks can tag their work with it if they want to.
Just a thought.
