I don't know how many people are actually subscribed to this list, or if this will make much of a difference, but I'm one of the founders of Orain, a wikifarm. We're nonprofit, open source, and ad-free. 

We just recently launched an Indiegogo campaign to help stabilize our resources and stay online, while remaining ad-free and nonprofit. Our campaign is doing fairly well, we're at 35% of our goal, but I was hoping that someone, anyone really, in this list could donate? Even if it's just a dollar, it pushes us that much closer to our goal. 

Of course, if you have any questions I'd love to answer them. 

The campaign is here: http://igg.me/at/orain
