We’re enabling two experimental importers today. This is to help out the tons of people who have been writing in saying they want to import their content from the systems they were using before WordPress.com, and especially for the brave few who were copying their posts by hand, one by one. (I wish I had that sort of patience!)
First we’ve enabled an importer for Blogger, which is pretty much as simple as we could possibly make it. You simply input your Blogger username and password and it goes and grabs all of your posts and your blogger comments, and brings them into WordPress.com. End of story.
Next up we’ve activated the importer that works with the type of files exported by Typepad and Movable Type. (They export the same files.) This is a little bit more complicated, what you’ll need to do is export from their respective interfaces and it’ll give you a nice text file. Our importer will let you upload that file, and then we’ll take it from there, importing posts, trackbacks, and comments, and even allowing you to map authors from your old blog onto authors from your new one.
As I said earlier, this is still a bit of an experiment. If either of the new importers doesn’t work the way you expect it, let us know in the forums or by using the feedback link in your admin.
