I think you'll find that most clan societies have one, common prerequisite - that you use proper spelling in the 'Pay to the order of' line of your check.

Which does tend to beg the question of why most people join a clan society in the first place. While there are advantages to be had in some societies, because of the genealogical research effort of the society, the fact remains that we are who we are and no membership card required. I've yet to be charged annual dues to pull my chair to the table at a family reunion.
