Private?

I have contemplated making my blog private, but my friend just posted these instructions on her blog to make it partly private- so it can't be found in search engines, etc. Anyone with your address can still get on easily and you can still reach your blog through links off your friends, but it is just a little security from FREAKS if ya know what I mean! Anyway everyone should do these simple instructions written by Christina Barrington- I hope she doesn't mind me plagarizing!
There is a way to avoid all this. If you haven't done this yet, do it. It makes it so that your blog doesn't come up when people click on your name (in comments) and also removes your blog from public listings.
"Once you're signed into your blog, on your dashboard go to the "Settings" tab of your blog. Then, under the "Basic" tab on the left going down, you'll see "Title" "Description" and then the two all important "Add your blog to our Listings" and "Let search engines find your blog" Set both of those to "No" and scroll down to "Save".Then back out to your Dashboard to "Edit My Profile" and down to "Show My Blogs". Click on "Select Blogs to Display", click "OK" in the little box that comes up (because you probably haven't changed anything on that page and it's just being paranoid).You should now see a page that says "Set Displayed Blogs" - un-check everything and then click "Save Settings".
