- Dashboard–>Manage–>Export
- Save the xml file to your disk/USB.
- Start a new blog at WordPress.com or Edublogs
- Dashboard–>Manage–>Import–>Wordpress
- Done.
You could start your own blog on a shared server, but for true blog freedom, master your own domain and install WAMP MAMP or LAMP and WordPress yourself.
I don’t plan on “pruning” the server database till the fall, but export before you leave in June.
