having a separate fundraiser targeting logged-in users. if it raises the required amount, put it towards going carbon neutral. if it doesn't, well, some more shrapnel (small change) for WMF. I also agree it would be better on the wikimediafoundation.org site rather than, say, the footer of every WMF project page. -- Brianna Laugher
Could that money then be used to get the Tampa server cluster to use renewable energy, e.g. (quick Google, I'm not connected to them) the Tampa Electric's Renewable Energy program http://www.tampaelectric.com/environmental/renewableenergy/?
