I guess I should take this opportunity to point out a philosophical difference between Virtualmin and Webmin, and what that means for the way you interact with the system (and why Virtualmin+Webmin is vastly more powerful than any other product on the market…though it may seem more difficult to use if you don’t grok the differences between these two distinct, but very tightly integrated, tools).
Webmin is a general purpose system administration tool. It’ll do nearly everything you would ever need to do on the command line from a web-based UI. It is not designed to make system administration “easy”. It is a tool for people who know how to administer UNIX systems. It can make learning system administration somewhat faster (because it hides stuff like the complexity of configuration files–Webmin always gets the syntax right, and you don’t have to check man pages or search the web to be sure), and it can make it easier for people who aren’t deeply familiar with every specific service on the system keep things running. But, it is not, in any way, designed to compete with Plesk or cPanel. They are completely different tools with completely different audiences…those audiences happen to have a bit of intersection in the web hosting market, though, so Webmin is very popular amongst administrators of web servers…sometimes even beside cPanel and Plesk. But it doesn’t compete with them, and never will (it also has an order of magnitude more installations worldwide than cPanel).
Virtualmin, on the other hand, is designed to make things easy. It’s goal is to remove the majority of the tedium and repetition, as well as a large swath of visible complexity, from a web hosting system. It doesn’t do nearly as much as Webmin (Webmin has 114 standard modules and a couple hundred third party modules…no web-based administration tool does as much as Webmin), and is merely one more Webmin module. So, when you’re looking at the Virtualmin menu in a properly configured Virtualmin system, you should be seeing the most “easy and automatic” way available to do anything. The moment you click “Webmin”, you’re leaving “easy” and going over to “comprehensive and flexible”. There are a few occasions where you have to go over to Webmin to configure things that effect Virtualmin, but that’s rare, and usually means you’re entering a world of things that no other product can do.
This duality of purpose has some drawbacks…as you’ve noticed it can sometimes be hard to find things, because there are so many possibilities. We’re working on making this better. The UI is getting upgraded with just about every release. We added module search a while back, there’s pretty solid documentation for most of Webmin in the Webmin wiki (and things will get better and more nicely searchable in the next version of the website, when everything at Webmin.com and Virtualmin.com gets merged into a single system with shared bug tracker, wiki, and forums–once that’s done docs search within the product will get better, too). But, that “Webmin” menu is always going to lead to a place where you’re expected to know what you’re doing. (Even if, “know what you’re doing” means “looking at the documentation, and comprehending it”.)
