As many other I would really like to get a way to add the post title (or something else identifying the post) to the email sent. As many, I use the same contact form on multiple posts, and would like to be able to on the email to see from which post it was sent.
I noticed that the contact from is included in a post using a text like:
[contact-form 1 "Hello World"]
An optiofor me could be to somehow be able to see the post-specific text "Hello world" to my email message (or subject or whatever).
I would guess, though, that most others will find the possibility of adding the post title a better solution.
