Hi Simon, welcome back. *Waves. And nice to meet you, (I don't know you because I am a newbie)
This place could use some advertising indeed. The post section for visitors on CC's own Facebookpage isn't available any more. Accept when they post something themselves, then people can reply. But last message is from 21 october, so yeah, not much action there.
I am not in the Facebook group Merry Murder, so I can't use that either.
I follow the group countingcrows_dreadheads on Instagram, I could try there.
