Is it possible to create a scrolling announcement message that can show at the top for all customers so we can provide announcements of outages and such for them.
Would the Announcement Feature (in the General section) give you what you want? You can define an Announcement that displays on just the Admin portal and/or the User portal and you specify the time frame for the Announcement to be displayed.
That feature is not currently available in the non-cloud version. Would be nice to have it though
