Photos Using a concept called \'tagging\', flickr has caused a revolution in the way people share photos online. Signing up for an account is free and you can upload your photos to your account right away through your web browser (you can also send them by email to a special address, meaning that if you have a fancy mobile you can upload photos wherever you are). Once they\'re there you \'tag\' the photos with some descriptive keywords and can see all the photos which have been \'tagged\' with those same words. So, the very easiest way to join in with our experiment is to sign up to flickr, upload some photos, and tag them with \'greenbelt2005\'. Learn more about flickr here Bookmarks del.icio.us does for bookmarks what flickr does for photos. Rather than storing your bookmarks on your computer, perhaps creating folders to roughly categorise them, del.icio.us lets you store them on their servers (meaning you can access them from any web browser) and again allows you to tag the links you\'re storing. As with flickr, signing up is free. Upload any links you find relating to Greenbelt 2005 and tag them with \'greenbelt2005\' and we\'ll quickly build a great collection of Greenbelt \'05-related thoughts and recollections. Learn more about del.icio.us here Blogging For those who have a blog, you can go one step further, by adding tags directly into your blog entries. By putting the following code at the bottom of your pages:

greenbelt2005

and then by typing your blog address into the form at www.technorati.com your entry will automatically be added to our GB \'05 collage. Learn more about Technorati here ............................ Meanwhile, we\'ll be working on creative ways to bring together all this content. So, watch this (hyper)space!
