As professors, you have so much information to share with the academic world. More likely than not, you created a domain with the intent to share that information, including your CV, membership on scholarly boards, etc. It is also extremely easy to create specific sections on your website for each class you teach in an effort to foster class collaboration and response. These sections are called subdomains. When you want to create a separate site without registering a whole new domain, create a subdomain. In fact, support.musites.org is a subdomain. Other examples of subdomains include finance.yahoo.com, docs.google.com, drive.google.com, and documentation.cpanel.net/.
With those examples in mind, a subdomain enables you to add a word or two in front of your main domain name in order to create a URL that links to an entirely different designed page. Applying this to your situation, if you wanted to create a couple differently-themed blogs, you could call one sports.myblogname.com and another one food.myblogname.com. Creating subdomains within your existing website is a great way to branch out and address different audiences and topics without drastically changing your existing site.
Because the MU Sites server is a shared server, please do not keep sensitive FERPA/HIPAA information, such as grades, on your site. You may be at risk of violating FERPA/HIPAA if you do.
Creating a Subdomain
4. A confirmation message appears when your subdomain is created. Your new subdomain doesn’t have a CMS installed. You need to install a CMS in order to add content to the subdomain.
