I was thinking along the lines of inviting a photographer along, the event would perhaps be a vehicle to promote the club to improve public profile, thus enabling us to pursue better deals with suppliers and perhaps enabling advertising on the site to help with running costs.
I am only thinking aloud, I am mindful of one of the better aspects of this club (IMHO) is that it does not have too much of a commercial aspect. It however could be good to exercise a bit of buying power, giving 'members' some benefits. This might be a bit of a stretch as 'membership' is a bit of a loose phrase as we don't have much of structure (a good thing in my opinion)
