The Share This Page function is getting better and better. This is appreciated, because I have a friend who finds even simple things on the computer hard to do, due to eyesight and other issues.
I have two suggestions. First, put the page title in the email Subject field rather than in the Body. Most people like to see what the email is about before they open it.
The second is more general. I don't recall seeing the Share function in the change list. I think it would be good to publish the change list here for discussion. It would generate thoughts and interest.
