Just wondering if I could use my blogger.com blog on this site, and if so, where do I paste the url for it to make it appear on my posts?

I am wondering the same thing too!

You are welcome to add your blog to your signature

Jax girl, you'll need 20 posts and 20 days before you can use the signature option.

Wyndymoon, you probably have the option available in your UserCP to add a sig since you've been a member a while.

Hope that helps!
