Hi there,

This is my blog: http://wilderviews.wordpress.com

I want to get the CSS upgrade so I can edit the CSS to GET RID OF THE BLACK NAVBAR beloe the header. I assume this will be pretty easy. Can anyone tell me what to change (from what codeto what code) and where i change it within the stylesheet?

Thanks you in advance for your speedy reply.
