Thanks for the help - it's very much appreciated.
I an new to WordPress, and although I've spent hour reading in Help, I'm still not able to accomplish the three things I'm trying to do (yes, I'm frustrated, and feel like an idiot as well : )
1. I would like to add my own header that I've created. I am using the default Theme. I've read the code, messages inside it, and the Help areas, but to date I've not make any result in changing the header.
2. I would like to make the font size in the right side navigation just a little bit bigger.
3. I would also like to make the font color in the navigation a darker shade of blue.
Thanks very much to anyone that can help!
