11phoneman11, first of all -- are you using older Symposium, or do you have CCMS? What application will you be using for the readerboard (Symon, etc.)? The vendor for that readerboard application will ask you for a desktop login ID (sometimes they ask for sysadmin, but I always create one just for them). You will configure that in Server Utility.
Otherwise, the CCMA can provide a desktop version of a readerboard (ADD - Agent Desktop Display). Some centers use a pc/large flat screen type of set up to display a readerboard-type.
