What is the difference between the two types of SharePoint 3.0 Templates

From mail2web.com Wiki

There are two types of templates available for Windows SharePoint Service 3.0; Server Admin Templates and Site Admin Templates.

Despite the name, Site Admin Templates do not include site definitions. They are simply a different way of organizing and displaying existing lists, libraries and web parts for a specific scenario or use. Normally you would have to install this type of template on your own, but to make it easy on our customers, we have pre-installed them in our SharePoint 3.0 environment. When creating a new site or workspace, simply select the Custom tab to select a Site Admin Template.

However, Server Admin Templates do include site definitions, and can therefore be used to create a root website. They also include customized workflows, dashboards and additional functionalities needed to complete different types of processes or roles. If you are interested in activating a SharePoint site based on a different Server Admin Template rather than the default Team Work Site, then we suggest signing up for mail2web.com On-Demand Business Solutions.

If you already have an active Windows SharePoint Services 3.0 or On Demand Business Solutions account, you can create a new Site or Workspace and select the Application Templates tab to select a Server Admin Template.
