We have received requests from the MathJax community to accept donations in amounts less than those required by our Sponsorship program. In response we have added a Pledgie button to the MathJax home page, www.mathjax.org. Your contributions will help us continue to provide our popular CDN service, browser testing, prompt bug fixing, and new functionality and help ensure that MathJax will provide rock-solid mathematics display for your content and the enjoyment of your readers. Your help is much appreciated.
