I'm a seasoned developer and CMS consumer, but I've never used SharePoint specifically. Is there a website where I can quickly create and manage a SharePoint site, without installing the entire stack myself?
For example, if I wanted to learn Wordpress, I would create an account at wordpress.com. This would allow me to create sites, manage sites, create and publish content, change the look and feel, etc. with no installation or infrastructure required from my end. I'm looking for something roughly equivalent in SharePoint, even if it's limited in the scope of what I can do with it.
Edit: Trials are great. But ideally, I want something unlimited/free.
