I agree with Graham.

I was asked if I would like a stall at the previous festival. Fortunately I was away so I never took up their offer, but whilst the event seemed to be well-organised it seemed to be well out of the cycle for festivals (it was later than others).

The line-up seemed to be announced late too.

So I would like to see a festival or two under the organisers belt before I committed myself.

The site (I went to something else there) is superb IMHO.
