We used to do them a lot more often. Every other month or so, and around every holiday. I had a pretty rough year though and it meant we took a big break from them. I've wanted to get them going again for the longest time, so it's really nice to finally be able to.
And when it comes to the rules, I always try to ensure it's as open as it can be. So that anyone can contribute in any way. Whether they prefer videos or like writing. Or even if their interests span into the other side of filmmaking. I'd even accept Christmas related documentary reviews!
It's always fun seeing what people come up with, reading posts from new and familiar faces, and spreading some of that fun holiday atmosphere. One of the things I really love is seeing the engagement from the community. People making new friends and finding new followers to talk film and TV with.
