Along with the Official Eidos Tomb Raider Forum, run by the developers, many fan sites have forums and message boards for their visitors. Some of the more popular are listed below.
Other sites with message boards and chatrooms are listed in my Links Directory. There are also forums devoted especially to the Level Editor. See my Tomb Raider Level Editor links.
Wiki sites are collaborative projects that invite users to create and edit their content. "Wiki" itself is an acronym for "what I know is...", as well as the Hawaiian word for "quick". The most popular wiki is probably Wikipedia, which has subsites in many languages and covers a staggering array of subjects.
For the last two years I have led a team of Tomb Raider fans playing for Extra Life, a charity video gaming marathon to benefit Children's Miracle Network Hospitals. Together we've raised nearly $4,000 to benefit hospitalized children. We also had a blast playing our favorite games, livestreaming, and chatting with friends and fellow Lara fans.
We plan to do it again this year and hope
you'll join us. Extra Life 2014 is scheduled for October 25-26. If you'd like to be a part of Team Tomb Raider Community, you can sign up on our Extra Life Team page. Questions? Send me an email. For details about Extra Life, please check out my past blog posts here and visit Extra-Life.org.
