EDIT--I have not posted about this before. I'm not the aunt everyone is referring to but there were 2 posts about potluck weddings yesterday and I'm sorry but they are not acceptable. If you don't want to go into debt to pay for your wedding, wait till you can afford to pay for it or scale back. It is not the responsibility of your guests to provide their own meal and but you a gift. That not only makes you look tacky but greedy too.
