I already know how tasteless and rude it is to do the whole "I'm inviting you via FB to determine whether I should send you a snail mail invitation."
But I'm just wondering how many people are with me on this. Of course, I'm sure no one who's actually done/doing it will 'fess up, but maybe by starting this thread we can save other brides-to-be from committing the dreaded faux pas.
