C'mon people. The hashtag thing has been coming up a lot on here on the last week. Are you getting married at age 14? Your guests can figure out if they want to sit and tweet/instagram/whatever instead of party. If you want a hashtag, just put it on whatever pics you post leading up and see if people catch on. Selecting a cutsey hashtag and telling people to use it = generation z bridezilla. Worry about whether there's enough booze, great food, and a fun party, not a silly hashtag.
