Action Email Headers (Version 1.0) For Mozilla Thunderbird

On the 43 Folders website, Merlin Mann suggested that email authors should "consider adding functional text headers to the top of the body [of their email messages] outlining the exact nature of the message."
In his article "Writing sensible email messages," Mann proposed these headers should look like this:

This email is:   [ X ] actionable [  ] f.y.i.     [  ] social
Response needed: [  ] yes         [  ] up to you  [ X ] no
Time-sensitive:  [  ] immediate   [  ] soon       [ X ] none

I wrote a series of templates implementing these headers for the Quicktext extension for Mozilla Thunderbird. I am making these templates available to you, free of charge. Here's how to install and use the Action Email Headers:

1. Install Mozilla Thunderbird as your email client.
2. Install one of two Thunderbird extensions:
   
   • Quicktext (free)
   • Quicktext Pro (commercial)
3. Download headers.zip. Extract the archive to obtain headers.xml.
4. Import headers.xml into Quicktext (Tools->Quicktext, then File->Import->Templates).
5. Now when you compose a message, you'll notice three new menus in your Quicktext bar:
   
   • Actionable
   • F.y.i.
   • Social.
   These are your selections for the "This email is" category. Under each menu, you are given the choice of 9 combinations to complete the headers.

Any additions/corrections to the headers will be posted on this page. Please report any incompatibilities to David Fisco.
