The rainforest site is great!! You simply click every morning, and you save a few sq. ft. of rainforest. It's matched money wise by come conservation groups. It's driven purely by public interest. Your own special way of helping...... You register with the site, and then you can program it to remind you every morning. It has different trivia every day and is very interesting. http://rainforest.care2.com/
Have fun, and thanks for the interest!
