So the wedding hashtag that I've been dying to use is already taken by someone else. When searching it after posting mine they have the same one. I'm debating to change it or does it matter? I obviously don't know these people and don't know when their wedding is but I do know it's the same year (I'm assuming because it has a 16 at the end of it) I want to get a sign made (also for those who are using hashtags for Instagram how and where are you going to display it?
