User Suggestion: Allow cancelation of message

[JenMysoc]

Yesterday I sent a message to my MP but after sending and before verifying, I realised I'd made a mistake so started again.

However, I've now had a second reminder to verify my email address and send the message. How about an option in the email to cancel the message in question?

<- perhaps just a link that means people don't get send the second reminder? then the message doesn't get sent automatically.
