My team recently transitioned to GH and as a Scrum master, I find that being able to put project related notifications in a bulletin board type feature where everyone can view it will be very helpful. With the current GH version, there is no way of doing this, so I had to became creative. I am using the GH board name field to display some of the important info I need the team to know about. See screenshot.
Usage for a bulletin board type feature can be endless e.g. any project dates, quick project related info/alert team should know about, even inspirational quotes, just to name a few!

I would really would love to see this feature on GH and I know it will be helpful to many. Thanks and keep up the good work!
