at http://virtualmin-demo.virtualmin.com/ is a demo version. Why? if I can download it free. How can I see the pro version?
There’s unfortunately not a way to see a demo of the Pro version at this time.
You can see a list of differences between the Pro and GPL versions here:
There’s also a 45 day money back guarantee on the Pro version – if you buy it and find that it doesn’t do what you want, no problem, just file a support request within 45 days and your money will be refunded.
