So, for example, what I did today was to create some subdomains that point to my stuff online:
MyClassProject.LauraGibbs.net: points to my project from last semester; I'll update the redirect when I have a new project this semester
MyClassBlog.LauraGibbs.net: points to this blog
MyBlog.LauraGibbs.net: points to my OU Digital Teaching blog, but I am kind of ambivalent about that blog; I might switch to a different one someday
Diigo.LauraGibbs.net: points to the "laurakgibbs" account at Diigo, which is the more public one with all my story bookmarks
Flickr.LauraGibbs.net: points to the albums page for my account at Flickr which is definitely the best landing spot
To create a subdomain at OUCreate, there is a subdomain tool in the Control Panel. All you have to do is type in the name of your subdomain (I use the default root directory), and press "create."
It's easy! And you can have an unlimited number of subdomains. But for this to work, you have to choose the "domain" option at OUCreate which costs $12/year. The free option (___.oucreate.com) is actually a subdomain option itself, which is why you cannot create subdomains there. I would say the $12 is worth it just to be able to create custom subdomains. They are so handy!
