Madness Against Malaria is the latest event to raise money for African bednets.

From the website:

Madness Against Malaria is an initiative of the World Swim For Malaria Foundation (WSMF), a charity registered in the UK, US, Australia and a number of other countries.

In association with Lance Laifer of Dunk Malaria, Madness Against Malaria will match teams of malaria fighters in friendly competition to see who can raise the most money to fight malaria with insecticide treated bednets.  Bednets are a proven weapon in the fight against this deadly disease, which kills 1-3 million people each year - 70% of which are children.

You can help by sponsoring a team or starting one of your own.  To get started, visit Madness Against Malaria .
