I suspect I'm going to need an add-on for this and if so perhaps someone can suggest one that may already exist. What I'd like to do is put a banner under usernames when it is that user's birthday. I'm currently doing this by using the User Group Promotion with the "Today is user's birthday" criteria. However, it has come to my attention that by doing so we are ignoring users who, for privacy reason, uncheck the option to "Show day and month of birth." So, I'm wondering if there is a way to set a criteria for showing a user banner only when it's a user's birthday and they haven't selected to hide their birth date.
