If anyone else out there has a WordPress blog installed on their own domain name I would strongly suggest you put in place whatever security protocols you can to ensure your site isn’t hacked.

One of the great things you can do besides the obvious (i.e. change your username from admin and use complex passwords) is install a great security plugin like Better WP Security.
