Jonathan Protzenko, who worked with us over the summer, released Thunderbird Conversations the other day.
If you haven’t tried it out already you really should. We’ve been demoing it on the road for quite a while and I’ve been using it as my main way to interact with Thunderbird for weeks now.
Check out the TB Conversations Video for how it works.
Note: Thunderbird 3.3 is required for Thunderbird Conversations
See the Thunderbird Conversations post on the Mozilla Labs site for all the details.
