Thunderbird 2 is now available for download on Windows, Mac and Linux in over 35 languages. It offers easy ways to manage and organize your email with message tags, advanced folder views, message history navigation, find as you type, and improved new mail alert notifications. Thunderbird 2 also includes a refreshed user interface and support for Microsoft Vista.
Rob loves him some Thunderbird in the morning. Noon, evening and even late night as well. Great e-mail client! I’ve been using 2.0 beta for a while and have been pleased overall, although a few things have been moved around that threw me off course originally.
