One of the projects I have been a long time supporter of is Distributed.net. I have contributed computer time to it for over 2 years, and until recently there was no Tolkien related team (to my knowledge). There are teams relating to almost anything else imaginable, from computer advocacy groups to small groups of friends, etc.
Two days ago, resulting from a conversation with the Webmaster of Rolozo’s Tolkien, I created Team Tolkien to fill in the Tolkien gap at Distributed.net.
More information on Team Tolkien is available on the team page I created.
