Yeah, I didn't want to say anything, but since ddavidv brought it up, it sounds more like the local dentists setting up a Limited Partnership rather hobbyists getting together to share their interests and do something fun.
Get the fun stuff going. All that other stuff, if needed, will fall into place later.

The first and only model RR club I was ever involved with started with informal meetings in a chuch basement, in a room that, in time became the layout room. The early meetings, as I recall, were discussions, movies, clinics, etc. Just a sharing of knowledge, some fun and getting to know each other. The actual organizing with bylaws, etc somehow seemed to happen painlessly as time went on. I had to move from the area shortly after the club really got rolling but I think its success came from its structure that grew from the membership rather than inserting members into a structure.
