It appears I can display a notice to a single user if it is their birthday, but can I display a notice to everyone saying Happy Birthday to the users whose birthday it is on that day (without having to do it manually)
ie I would like a permanent notice set up, but which displays to all but only when someone has a birthday, and the notice mentions that User's birthday.
I wish, I would have known this before. You mean the birthday criteria does not make the notice recurring (even though it is not dismissed)? To me it is strange because at the time of setting date criteria, the phrase says, "Today is user's birthday" which gives an impression that it will appear every time it is user's birthday.
