Let you sign messages without encrypting

[ravenclaw900]

I really like the new signing feature, but it requires you to also encrypt the message to someone. Since most of the messages I send aren't to people with GPG encrypted email, but I still like to sign them, this would be great.

Sign only would be a very nice feature. Thx

If this it to be implemented, Id reckon its best to use the

---
message
---
signature
---

format so it can also be read by people not using pgp

Would love to see message signing w/o encrypting the message!

+1 this feature as well! Would be a very useful feature for me.
