I think another thing to boost morale as a whole is a uplifting positive thread in general for support. Some of the posters here go through some dark and trying times. Some have issues with family, loss, friendships, etc etc. So an thread of encouragement or inspiration might help take it to another level. Also I love watcher’s idea about clean humor. Also if a person post in that thread have some troubling times. Various members can pm that person with encouraging words, pictures, gifs, humor, love, poetry, quotes, whatever. Or they can link it in that thread itself. I have been in other fandom groups and one thing that really helped with bonding, was it was taken beyond the show to we were supporting each other through personal issues and crises.
Also a getting to know you weekly or monthly topic. Lets talk about your favorite movie, tv show, music. What was your first fandom or first ship. When did you learn the internet! 😀
I know we have some polar thoughts and opinions about the show, but we do enjoy a lot of things that are similar!
Just a few ideas to roll with!
