We used to have a Liverpool-based team, PaperTwin, on here but they've not been so active of late.
I'm sure there are a few Mancunians, but I think the best place to look would be Shooting People. I know that they regularly do Shooters in the Pub in Manchester/Liverpool.
Is Shooting People worth the subscription fee?
Worth noting...
Shooting people - subscription based networking website for people interested in film
Shooters In the Pub - facebook group for people in Manchester/Liverpool to meet up in a pub and talk about films.
