One interesting new trend we've noticed recently is the wedding ceremony phone check. It's a bit like a coat check, but for couples who would rather keep their guests from posting wedding updates on instagram, facebook, twitter, etc. during their wedding ceremony. 

We had a bride recently interested in this...and asked, "How do I go about this without pi**ing people off?" Great question...

Some of our suggestions:
 - ask the officiate to make an announcement
 - put a note on the program
 - ask your program attendants to ask guests to silence their cell phones

What ideas do you have?
