If you would like to give it a try, you will need either a nightly or
alpha version of Thunderbird, together with the nightly version of
Lightning. You can get these using the following links:
* Thunderbird 3.3a2: http://www.mozillamessaging.com/en-US/thunderbird/3.3a2/releasenotes/
* Thunderbird 3.3a3pre nightly:
http://ftp.mozilla.org/pub/mozilla.org/thunderbird/nightly/latest-comm-central/
* Lightning 1.1a1pre* nightly:
http://ftp.mozilla.org/pub/mozilla.org/calendar/lightning/nightly/latest-comm-central/
NOTE: (*) To avoid misunderstandings, even though it is named
1.1a1pre, this does not mean we have release 1.0 yet! Lightning on
trunk (labeled 1.1a1pre) uses a different Mozilla platform than
Lightning from the 1.9.2 branch (labeled 1.0b3pre). We have chosen
differing version numbers to make that difference obvious.
