My finace and I are getting married in August. We have accumulated all the typical registry things we need over the years and really don't want to have additional "stuff." We already have our honeymoon paid for and planned. However, we have lots of student loan debt and would like to save up to purchase a home. What is the proper etiquette? Is it acceptable to ask for "donations" to helping us out of debt, so-to speak? We don't want to be rude...
