Jetpack Contact Form Auto Reply

Works as it should in 4.9.8; I like that you can use {Field labels} in subject/message :)

Two changes would make this not just good, but great:


	 ability to have a subject/message per contact form (since you may have several forms with differing fields on the same site)
	the settings should be in the editor, where you define the fields (that would make the UI simple for keeping auto-reply-settings specific to one form)




Almost perfect

Send an automatic reply to anyone who fills in your Jetpack contact form
