(Product)^RED (RED is in superscript) is a brand name which works with other well-known brands to produce a product of which at least 1% of the profit goes to (Product)^RED, and this goes in aid of helping fight AIDS and related diseases. See http://joinred.com for information
Why not set up a (Wikipedia)^RED which would essentially be a skin through which the normal Wikipedia is viewed: it would change the colours to red (or shades thereof), have a different Main Page which explains the scheme and has inobtrusive advertisements on the side (under the interwiki links) which generate revenue to do to (Product)^RED (and Wikimedia).
I think that the aim of this is wholly consistent with that of the Wikimedia Foundation, and I would like to hear your views.
