FTP Site Banner or System Message

I'm trying to figure out how to setup a system message for my FTP server so no matter who logs in they will see this. I want to administer and change this message from time to time but only want to have to do it in a single place. In older systems they used to call this a Banner or System Banner but I can't keyword on either of those in SmartFTP help files etc.

Anyone out there familiar with this feature, or know whether it is possible with SmartFTP.

Also is there any function with SmartFTP that will allow me to FIFO files and/or folders off the server after a specified period of time - to maintain storage space.
