MathJax is used in displaying math equations and expressions more elegantly. I've seen it most widely used in the mathematics department of StackExchange. What I am inquiring about is if there is a site that is used solely for the purpose of writing MathJax code and displaying its translation. I would like to show a person my custom example using MathJax, but I don't know of any way of showing it to him. What would be ideal is if I could give him a URL that takes him to a site showing the content I've written in MathJax. Any help would be appreciated.
