I'm sure you are already doing this. But "The four best ways to manage your server

Virtualmin offers four methods for managing your server: Web, mobile device, command line, and remote API. Virtualmin is always available, no matter where you are or how you want to work."

Virtualmin is always available, no matter where you are. You can conveniently manage your servers through Web, mobile, command line and remote API.

I'd delete the entire paragraph following Try a live demo. Just replace it with a link saying live demo.

With the watch a video paragraph can't you put the picture of the video with a link and a play button on it here?

The little I know about writing I learned from "On writing well" - Zinsser. His chapter on simplicity is worth the price of the entire book.

"With the watch a video paragraph can't you put the picture of the video with a link and a play button on it here?"

That's a great idea. Why didn't I think of that?

I would make "Download/Buy Virtualmin" more prominent on the main page. In fact, I'd try to give it as much prominence as the "Find Out More" button.

At first, I was confused about whether this was a service or if it was shrink-wrap software for you to buy and install on your own servers. I suspected the latter, but didn't know for sure and was kind of frustrated that I couldn't tell. I clicked on the demo link and the "find out more" link before coming back to the main page and finding the "buy online" link down at the bottom.

Valid point. Whenever folks come to us through "web 2.0" focused channels there is the built-in assumption that it's a service. But, we want to help folks build services on their own servers. I'll spend a bit more effort on making the distinction clear, and making "download it now!" an obvious component (I'm in the midst of porting our automated installer from the commercial version to the Open Source version, so that'll make it easier...right now the GPL version is rather complicated to get spinning).
