It's hard to believe, but Second Life has been around for a decade now. Each year, a special event commemorates Second Life's birthday.
For most of the past celebrations, Linden Lab has been in overall charge of the event. However, last year when LL announced that they would not be providing special regions for birthday events and exhibits, and were leaving any celebrations up to the Residents...the Residents responded in their usual gung-ho fashion and put on what was undoubtedly the best Second Life Birthday exhibition ever.
This year, they're doing it again! There will be 20 regions of SL10B (woohoo!), and the theme is (appropriately enough) "Looking Forward, Looking Back".
The organizers are putting in an unbelievable amount of time to get this put together. And if you want to be a part of SL10B, you can! They need exhibitors, performers, volunteer helpers of all sorts. Check it out on the SL10B website, http://slcommunitycelebration.com/
Even if you don't get actively involved, do be sure to visit the event. It'll be open from June 16-29 (SL's official birthday is June 23). This is perhaps the biggest annual demonstration of just what Second Life's residents have done, can do, and look forward to doing in the future. It's an incredibly moving experience to see what people can do when they really put their minds to it. Don't miss it!
