The left navigation pane on a team site shows the Quick Launch which display links to many lists and libraries on the site. If you need to, you can hide the Quick Launch completely by embedding some style tags on the page. This is accomplished using the Content Editor web part. Furthermore, you can export this web part and utilize them on other pages as needed.

Deleting a SharePoint site is a fairly simple process. Only site administrators have the right to delete a site. A site with subsites underneath it cannot be deleted until all subsites have been deleted first.

Each site collection stands on its own and does not have a link to other site collections. However, it is a requirement many times to create one general Portal which ties all the site collections together. The Portal Site Connection functionality can be used for this requirement. In addition, this functionality can help users of My Sites tie their site to a central Portal as well.

List templates and site templates can be transferred from one site collection to another. Once you transfer a template to another site collection, it’s available for you to make sites or lists based on that template.

Lists are created using list templates. Aside from the built in list templates, you can create your own list templates as well so designers and administrators of a site can then use that template to make additional lists. When a list template is saved, it saves the list’s schema. You can also save the content of the list with the list template as well.

A custom site template can be created as a starting point for creating future sites. A site template can contain lists, libraries, pages, and even content.
