Hello, thanks everyone who was helpful in getting me started. I've actually got a few readers already, even though it's a bit scary (and amusing) to see what they were searching for.
I noticed on google, if I search for my url, such as "myweblog," the first thing that comes up is a link to ... wp-admin/index.php, which is my admin page. Is this something I should be concerned with, even though I have a password? Is there a way to prevent this page from being indexed?
