It is a fundraising thing for the Mothering Board. The 'size' of the donation is not significant - just donate above to the 'Community Chest' and then PM 'DDDDC' with your information of the 'who' and 'what' that you would like DDDDC'ed. It takes a few days to show and stays for about a week.
Do a search on DDDDC in the Diapering Forum and you'll see some of the havoc we throw upon each other! :LOL
