Pledge challenges

Pledges have been posted on 29 December. See details further down on that day. Design your own pledge or challenge any of the existing pledges. It's fun for a good purpose. Any person or organization wishing to take up the challenge can either post his commitment directly on this blog or can e-mail his pledge to Gerhard Odendaal at gfo@iburst.co.za' who'll publish your pledge on the blog. Your pledge can also be based on anything else which you may prefer.
