false ONLINE and when you give click to redirect to a URL
something you should add to your system is that when this "off" you can place a false ONLINE and when you give click to redirect to a URL that can be a ticket system for example.
Unfortunately this would be misleading your Visitors because you would be offline while Visitor thinks you are online. That is why we have an offline form for which you can add a little banner.
Hope this helps.
