I was asked to join this band at the audition and said yes, but since rehearsing with them once more I have changed my mind for various reasons. I was just wondering what some folks opinions were around here about letting them know I quit via email. I'm just asking because the last time I was in a band was so long ago that I didn't even have an email account yet! So that's why I'm wondering what the protocol is these days. What do you think? Acceptable or rude?
