Hi, Superjacent, welcome to the forum. Any time you want to edit the way your blog displays, you actually want to edit the skin you're using. Open up /skins/<skin you're using>/_main.php and you can find the sidebar in there and add your code.

If you have trouble, paste in a link to your site so I can see what skin you're using.

Thanks for your quick reply, that helps heaps. I've now included my blog in my signature, should have done that to start with.
