Rodent Regatta

OK…I typed some stuff. Then, I posted it. Now I see what I typed with a checkbox next to it. What am I really looking at? Is this the way everyone else will see my weblog site? There are so many things here that I like, but I’m not sure how to change them or edit them. How much of what I’m doing cannot be undone when I really learn what I’m doing? Can the title be different? Can the footer that contains the copyright notice? How do I manage the links down the right side of the page?
I’ve just downloaded the trial version of Radio 8.0. Where’s the primer that gets me into the other features? I love this stuff.
