Compasses management is fine about using the Green Room [the one to the right as you go in the front - as used by the MEMWNS Xmas Do, Huffers and Puffers etc]. Starting 8pm as planned, probably get there earlier if you want food.
There are only 2 B&B rooms left for Saturday night [out of 5] so get a wiggle on if you want one! Travelodge in Dunmow seems the best alternative, [floor space at Tomsk Towers if necessary].
Camping in the beer garden is ok, though there is Seward's Hall site up the road in Felsted too.
Once the Flatlands is out of the way, I'll give some thought to agenda [nothing too formal, no flip-charts or powerpoint planned], at least so those extremely helpful Anciens and Anciennes can dredge up their memories.
