Is there a way to mirror a blog to a secondary domain name? I want to do this to support people's complaints that some people prefer to see the entire article (not using split posts) and some people want the posts split.
Also, it would be nice if there were a mobile-device friendly theme that I could use as a third domain name. Any chance wordpress.com will support the m prefix to the domain? I know there's a wordpress software plugin that does this automatically, but I was hoping to avoid hosting my own site.
