Mozilla Thunderbird 2.0 has just been released. I have been using Thunderbird 1.5 to manage my personal e-mail (I use Lotus Notes for my work related e-mail) for a long time now. I also use it as my news reader and it's one of the ways I track several blogs. I just upgraded one of my machines to Thunderbird 2.0 to check it out and so far all seems well. I like the subtle improvements that have been made to the UI. I have not yet had time to explore and understand the full set of new features and enhancements that have been added. The new e-mail tagging feature looks interesting. I'll post more after I have had a chance to give it more of a test drive.
