Want an option to forward a blog posting via e-mail

What I’d like to be able to do is this:

I’d like people who read a blog posting to be able to click a link at the bottom of a posting that allows them to forward the posting via e-mail. When I was still using blogger, there was such an option in it, and I and my readers used it a lot. There was also an option to have all postings e-mailed to myself…which was very handy!

How would I go about doing either or both of these things? Are there existing plugins? Couldn’t find one no way!
