Or do what the Fender Precision Club does: the number of your first post becomes your number.Just what is an appropriate self-selected number that's not too arrogant, nor to humble? At least when you are assigned the next sequential number, like in most clubs, you don't have to agonize over what it says about you, if it makes the right impression, without hubris or affectation.
