Thanks John, all good now, just one more question. The main user on my blogsite uses Windows Live Writer and wishes to set the blog so that only registered members are able to view the posts. So I password protected the directory from within my C-Panel, however this locks out Windows Live Writer. How can we make it so that the blogsite requires you to register in order to view the posts. And she does not want to lock every post individually. Any ideas?

@justincsecs
I suggest that your post deserves a specific post in the b2evolution support forum.

It's lost here, attached to an old post on CSS.

I have little knowledge and even less interest in Windows Live Writer.
Sorry :)
