Below is the message that I found in Wikipedia this morning. For those who can afford to and value knowledge, you may Visit any Wikipedia page to find the message and make your donation.

To all our readers,
Please don't scroll past this. This is the 1st time we've interupted your reading recently, so we'll get straight to the point. This Thursday, we ask you to protect wikipedia"s independence. 98% of our readers don't give; they simply look the other way. If you are one of our rare givers, we warmly thank you.

If everyone reading this donated $2.75, we could keep Wikipedia thriving for years. The price of a cup of coffee is all we need. We're sure that you're busy and we don't mean to interrupt you but we must remind everyone.
We don't charge a subscription fee and Wikipedia is sustained by only 2% of our readers. Without reader contributions, big or small, we couldn't run Wikipedia the way we do.

We know most people would ignore this message, but we hope you would consider supporting Wikipedia today.

We want to make sure everyone on the planet has equal access to knowledge, and we need your help.

If Wikipedia has provided you with $2.75 worth of knowledge this year, please take a minute to secure its future by making a donation. Thank you.
