Alfresco is an open source document management system. Commercial users can purchase a package (Alfresco Enterprise) while those not looking for commercial support can pick up the current development snapshot, known as Alfresco Labs. The difference is that the non-commercial offering is not guaranteed in any way; just as with any other open source package, you use it at your own risk.
The commercial arm's main page is at http://www.alfresco.com/, while support for the non-commercial distributions is via the Alfresco Developers Wiki.
Concepts
An Alfresco installation is based around one or more sites. A site is a location in which documents are stored and sites my be either public, meaning that anyone may use them, or private, meaning that you must have a password, issued by the site's owner, in order to access each individual site.
Sites are assumed to be persistent, in the same manner as a web site. When you create a site, you define both a name for the site and a URL. The name of the site, although essential, is basically a tag. The URL, on the other hand, must conform to WWW conventions for naming, so that it can be used with Internet/Intranet access.

Site Creation Fails
You attempt to create a new site and instead get an error of the form:
Failed to load script... ...Illegally formed XML Syntax.
This appears to be related to the browser, possibly to do with cookies being time related. Try logging out of the browser and logging back in, you should now be able to create the site.
