I think I have it!
While I was looking through some blogs and some very lovely projects I found this 'How To' by Connie on how to add a signature to your blog. This link will get you to where you need to be to do this http://conniekresin.blogspot.com.au/2012/03/how-to-add-signature-to-your-blog-posts.html
As I am not completely computer literate I found this to be very helpful... Thank you very much Connie.
