Wouldn't it be nice to be able to leave a clickable link back to your blog or to a website that you want to share? I know this was a source of frustration for me, at least for Blogger Comments, so I finally Googled it and here it is.
Also, when you go to leave a comment (I LOVE COMMENTS AND FEEDBACK), you'll find a link back to this post in the Message above the Comment Box. I tried to post the directions there, but I couldn't because it would become a link and if I tried to change anything it would give me an error message and not let me post it.
Good Luck! If you have any questions, I doubt I'll be able to help but I'll try.
