If there's a {No contact email} following their name at the top of the message, they can't be contacted.
The only person who leaves an email is the originator of a message. Anyone leaving a Reply can't be contacted.
Use the Contact Editor link at bottom of each page telling me the name and reason you wish to contact them. I'll pass your message and email on to that person.
I'll need the message date (example: 3rd January 2017 at 9:36 PM) at top of each message, as searching the database for 'John from Leeds' might bring up 25 results from over a 1,000 messages.
For privacy reasons, I cannot release anyone's email without their permission. If they don't contact you, they may not want to (as I've had someone do this) or more likely no longer use that email address.
