I may have missed something. It happens from time to time.
I read a lot of the xmas in july thread (can we bring PET bottles, no you can't you *******, I'll cut your head off with my manifold etc etc) and I put my name down as a non swapping attendee but I haven't seen anything about a brew day until now.
As a partial masher, I'm very interested in observing, taking home some wort and certainly in contributing ingredients. Are there further details for this thing? Sorry if I missed the blindingly obvious.
Cheers
