Grammatical error on your website

To whoever writes the content for this page http://www.w3.org/standards/webdesign/
 
There is a grammatical error in the second sentence of the first paragraph. 
 
The sentence currently states “This section also includes information on how make pages accessible to people with disabilities…”
 
The sentence should read “This section also includes information on how to make pages accessible to people with disabilities…”
 
It’s not a big deal but I thought you might want to know considering your authority on the web.
