So you won't confuse it with the main blog. Feel free to fool around with this blog - there is nothing you can do the blog that'll hurt the main blog. Do toy around with the graphics and other widgets. To add a graphic an URL, just choose the widget with a tree, when it opens up, upload the photo with the image you want (remember, your sidebars are at 250 pixels wide), and paste in a URL. I often use Ordinal's SLurl generator for SL stuff. Other than that, you can Google Blogger widgets, or you can go to "Blogger Buster" - the lady who runs it has a ton of neat stuff! See you later on!
