During my efforts to configure mailboxes, on failures , I had revived something called alert as a yellow bar over the screen everywhere (e.g. over dashboard). I knew such alerts could be created on the forms with java but this one really useful specially for announcements and also some important incidents some individual may need to consider. Best of all was that the alert was aimed at specific user.
What I need to know is if there is a way to create such an alert through workflow.
