I have emailed my tech support to upgrade this blog to the latest Wordpress files version 2.2.1 for better security. All the upgrades are done by my technical support online and a fellow blogger. You will need to export your database to save it or backup online via PhpMyAdmin dashboard. And you need to know which buttons to check and select for the database backup. It is good to backup before you upgrade to a newer version just in case. I have gotten my two other blogs upgraded already and they are running fine without any glitches.
