I hate to tell you this Flow... but you try 'site help' yet?
Make sure it's an 'M' flagged account to see the full list.
Site close (with a variety of options) along with a reason already exists and users trying to login giving a valid user/pass will be told the site is closed and why if a reason was given... You can even exempt any users you want from site closures. Site shutdown (with an optional grace period) exists as well however you can't give a reason right now. It's simple enough to add a reason if you want that.
v7.6 offers a new option to site close to close the site to normally exempt users except the user issuing the command and one other permanently exempt user (usually ioFTPD) in the config file. This is primarily for system maintenance type operations where you don't want anybody online while the system is in a fragile state. I even offer the ability to open/close the site via TCL now and have changed the startup logic so you can script the server to start closed so nobody can login.
