I have been providing some help to Home-Start East Herts this month. They are about to run a fundraising scheme called 100 Schools for Home-Start.
One of the issues in running such a campaign is how to do it effectively through your website.
Depending on when you are reading this it may have changed. The home page can be located here: http://www.homestarteastherts.org.uk and looks like this.

So anyone arriving at this site will see the large orange bordered box on the home page and the title 100 Schools for Home-Start. In this case the image and text below changes every few seconds with some different messages. Clicking on the Follow Me link or on the changing image will take the viewer to a special page where the Value Proposition can be presented and then the Call to Action executed by inviting the viewer to support the initiative and provide their contact details in a specially created form that sends a message back to the Home-Start organisation.
If you want to do something similar on your site, drop me a line.
