How to Put Signature In Blogs?

[LoudBox]

I want a signature to show in each blog entry as well as in each comment to the blog entries.

I've tried adding this to blog_entry ...

<blockquote class="signature restore"><div class="signaturecontainer">{vb:raw post.signature}</div></blockquote>

However the signature doesn't show.

What code do I need to put in there for the signatures to show?

Thanks!
