Lettris is a curious tetris-clone game where all the bricks have the same square shape but different content. Each square carries a letter. To make squares disappear and save space for other squares you have to assemble English words (left, right, up, down) from the falling squares.
Boggle gives you 3 minutes to find as many words (3 letters or more) as you can in a grid of 16 letters. You can also try the grid of 16 letters. Letters must be adjacent and longer words score better. See if you can get into the grid Hall of Fame !
Change the target language to find translations.
Tips: browse the semantic fields (see From ideas to words) in two languages to learn more.

Originally launched as Minotaur shortly after Phoenix (the original name for Mozilla Firefox), the project failed to gain momentum. With the success of the Mozilla Firefox, however, demand increased for a mail client to go with it, and the work on Minotaur was revived under the new name of Thunderbird, and migrated to the new toolkit developed by the Firefox team.
Significant work on Thunderbird restarted with the announcement that from version 1.5 onwards, the main Mozilla suite would be designed around separate applications using this new toolkit. This contrasts with the previous all-in-one approach, and will hopefully lead to more efficient and maintainable code, as well as allowing users to mix and match the Mozilla applications with alternatives.
The original Thunderbird logo was just a modified Firebird logo, with a simple shifting of hue value from red to blue. In 2004, together with the change of Firefox's visual identity by Jon Hicks, a more professional logo that is currently in use was introduced.

On December 23, 2004, the Project Lightning was announced for tightly integrating calendar functionality (scheduling, tasks, etc.) into Thunderbird. Lightning is just a project name, not a product name. Lightning 0.1 was released on March 14, 2006. The current version is 1.1.1, which was released on January 5, 2012.
On October 11, 2006, Qualcomm and the Mozilla Foundation announced that "future versions of Eudora will be based upon the same technology platform as the open source Mozilla Thunderbird email program." The project is code-named Penelope. An unofficial Eudora/Penelope forum is accessible via web or newsreader.
On July 26, 2007, the Mozilla Foundation announced that Thunderbird would be developed by an independent organization, because the Mozilla Corporation (the for profit portion of Mozilla) is focusing on Mozilla Firefox development. This change was made in order to stimulate development in Thunderbird, which was being neglected during the Mozilla focus on Firefox.
On September 17, 2007, the Mozilla Foundation announced the funding of a new internet communications initiative with Dr. David Ascher of ActiveState. The purpose of this initiative is "to develop Internet communications software based on the Thunderbird product, code and brand".
On February 19, 2008, Mozilla Messaging started operations as a subsidiary of the Mozilla Foundation responsible for the development of email and similar communications. Its initial focus was on the next major version, Thunderbird 3.0, which was released on December 8, 2009.
