I'm wondering about the best way to do this. What I want is to start a blog here at WP.com and basically practice on it (including CSS) then, when I am ready to commercialize it, move it to outside hosting and use WP.org software. I'd like to do this using one domain name, ie register through WP.com and then keep the name when I move to off-hosted WP.
My question is, how smooth is that transition? I can transfer the content no probs, but what about the name? Has anyone done this yet? It makes far more sense to start with the name you want to end up with and perhaps build a following and a Technorati ranking than to essentially throw away any attention you've gotten before the move, but naturally I'm being overcautious and want to know what's involved in keeping the name's portability. Can anyone do a quick Walkthrough for Dummies?
