Forward a complete conversation/thread in Gmail?

Question

I have a long chain of 20+ emails in GMail I wish to forward to someone else -- I don't want to forward them individually. How can I do that?

Answer 1

In the latest GMail, you can do this via the "More" menu, if you have the conversation selected:

Click More, then click Forward All. This results in a new email sent to whomever you choose with all the emails in the conversation / thread in a single email that looks like this:

Forwarded conversation

Subject: Subject

---

(all the emails in the conversation / thread will be included in the body here as one giant email)

And this forward itself ends up being part of the original conversation, so I don't know what happens if you forward a conversation twice. :)
