title: Open Source Grammar Checker
body: <p>For an online project I'm working on, I am looking for a open source grammar checker.  I have searched Google, with some good results (<a href="http://www.link.cs.cmu.edu/link/" rel="noreferrer">http://www.link.cs.cmu.edu/link/</a>, etc), but I am wondering what all of you think about this topic.</p>
  
  <p>I need this to be able to be used online, versus desktop based, but this is the only real specification I have.  If it has a built-in spell checker, that would be a plus, but I can always use another project for that purpose.</p>
  
  <p>Thanks for any help.</p>
