Magpies,
It really depends on how much detail you want on the site... Using free site builders you could set up a simple one with info about the club, history etc. On the other hand if you want to start keeping track of fixtures, generating tables etc (without going mad or spending hours doing it) it would be a different kettle of fish. There are some sites/software that do this for you but as A face said their generally crap, the other alternative is to pay someone to do it. As I said, really depends on what you want.
