These are cut from the by-laws, the chapter by-laws state only a Pres, V.P. and Treasurer are required.
Simpliy,
The Pres presides over the meeing and keeps things on track and the discussion moving along.
The V.P. acts as the "supervisor" making sure the business gets done. The V.P. is that teacher that stood over shoulder in Jr High seeing what you were doing. Th V.P. needs to know what the curent business of the club is, who is doing what, and is it getting done.
The Recorder keeps the records of the club, tallys votes, makes sure all of the leagle paperwork is done, and makes sure all of the club documents are accounted for.
The Treasurer counts the money, makes sure that the bills are paid and everything is accounted for.
Directors are the "voice of the people" they are the "house and senate" if you will, there votes are the ones that realy count, if the officers of the club want to do something they must convince the dirctors to vote accordingly. The dirctors also are assigned "special" tasks, like land use person, or events person, membership person, even a web person, what ever special jobs come around, they are assigned to directors.
I STRONGLY recomend you come up with your own by-laws and adopt then. Cut and paste these up if you want.
To speed things up, adopt the national by-laws as your own and write some when you have time.
Hope this helps
