If you’re leaving ISB you can take your blog with you! You export it from our WordPress site and import it to another WordPress site. Here’s how.
From your blog’s Dashboard go to the Tools menu and choose “Export.” Save the export file somewhere that you will have at your new home like a portable hard drive.
When you get a new WordPress blog, go to the Tools menus and choose import and upload your ISB blog.
The screenshot below shows what settings to use to export your blog. (Click on the picture to enlarge it.)
