If you aren’t a site administrator, then you won’t have permissions to create a new SharePoint site. In this case, you need to request it. Most organizations have a process for requesting a team site. For example, you might send an e-mail request to the SharePoint administrator or fill out a form.
Whatever you have to do to get your SharePoint 2013 team site, get one. At a minimum, you need to provide your SharePoint administrator with this information to get a team site:
The site name: The friendly caption that appears in the header of your site and in any site directory where your site may be listed.
The site template: The template determines what kind of site SharePoint makes for you. SharePoint includes dozens of predefined site templates. Your company may even create its custom site templates. Tell your administrator you want a team site, which is the most popular of all the SharePoint 2013 site templates.
The web address or URL: The unique location where your team site is hosted. In most organizations, all team sites are located off the same root web address.
Your organization may also ask who has permission to access the site. By default, all SharePoint team sites have three basic kinds of users, which are called SharePoint groups:
Visitors have Read Only permission. They can view your site without making any contributions.
Members can participate in your team site by uploading and editing documents or adding tasks or other items.
Owners have Full Control permission to customize the site. As the person requesting the team site, the SharePoint administrator likely assumes that you’re the proud owner unless you specifically tell him or her who owns the site.
You need to decide which users fit into these three SharePoint groups. SharePoint offers more than just these three groups, and you can create your own groups to meet your needs.
Your site’s users must be connected physically to your network or have permission from your network administrator to access your network remotely. Some companies set up a special kind of deployment for SharePoint, called an extranet, that provides a secure way for non-employees to log in to their SharePoint team sites without actually being on the internal company network.
Setting up SharePoint in an extranet environment can be done in lots of ways. Configuring a SharePoint extranet in your company’s network can be complex. However, the good news is that SharePoint Online, which is part of the Office 365 suite, eliminates many of the technical barriers to creating an extranet.
