The Meeting Workspace uses a master page, named MWSDefault.master, and stores pages in a hidden document library named pages (Workspace pages).
In the browser, you can create a Web Part Page based on one of the eight built-in Web Part Page templates.
In SharePoint Designer, you can create an ASP.NET page and then attach a master page to give it the look and feel of the SharePoint site.
You can create a content page from a master page, but you can add content to the page only if you make at least one PlaceHolderMain content region editable.
Web Part zones can be inserted only in content regions on content pages; they cannot be inserted on master pages.
There are two types of Web Parts: List View Web Parts and built-in Web Parts. List View Web Parts display the contents of SharePoint lists and libraries.
Web Parts can be inserted outside Web Part zones on content pages and master pages on by using SharePoint Designer. These are known as static Web Parts.
Web Parts inserted into Web Part zones are known as dynamic Web Parts. Details of dynamic Web Parts are stored in the SQL Server database separate from content pages and master pages.
Any pages or files you delete in SharePoint Designer are stored in the Recycle Bin, from which you can restore them.
