If I make it, this will be my second.
I must admit, being very shy for my age, I was a bit worried about what happens and when. I introduced myself to a couple of people when I arrived, sorted my hammock out and got a fire going (different site), had something to eat and generally kept myself to myself - it was dark so seemed pointless introducing myself to anyone, I think I managed a bit of a chat with everyone the following day then went home - I was soaked.
From that, I'd say - do pretty much what you want, everyone seems friendly enough to welcome you in if you want to get stuck in.
Or, if like me you're happier minding your own business most of the time - people don't seem bothered by that either.
Without wanting to tell you to suck eggs, what have you got planned to sleep in? I was happy in december in my hammock, tarp and BIG ex army sleeping bag with ex army sleeping roll under me. And I'm pretty sure I'd be ok down to about -8to-12c But people on here will no doubt be able to say whether you'll be warm enough or not (assuming you want the advise).
