Well, It appears you've found your way to my discussion board. I'm using just one of Phil Greenspun's free web services. I urge you to follow the links to his website and explore. Greenspun is an iconoclasitc web guy--he is very vivid--well worth the time! The tools he provides are industrial strength. If I were to set up an independent learning environment for online ed I'd build it around this software. For a heavy duty version look at Phil's site (a couple a hundred thousand hits a day?) and see how the discussion threads work. Phils site: http://photo.net/photo/ Check out the discussion on Nature Photography.(posted 9158 days ago)Thanks for dropping by. Explore my Saab site a bit ( if you have a taste for old Swedish iron). I'm getting about a 1000 hits a month. The site's design is very much in the 'Greenspun manner'
