All of those ideas will work, but Mark S said, if they don't want to read it they won't.
I just want a way to "SHOW IT" to them and a positive action to get rid of it. Read it or not, they had the opportunity.

Even the Global Announcement won't work because when they use the "Active Message" tool to come in they go right to the message and don't see the Global.

I just can't come up with a way that isn't fool prove.
