The InformationBar displays the content of a field in an InformationBar similar to the one used by Internet Explorer. Ideal to make sure that all users of the database know critical information about the current record.
See this video on how to set it up.
How it works: the bar displays the content of a field you choose when adding the bar to the layout. It pops up only if the associated field contains data. Since you might not want everyone to be able to edit the field thus to change the content of the infobar, you may want to use the User Restricted Memo Field that allows you to restrict access to the field to any user you want.
