Problem
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 (http://www.link.cs.cmu.edu/link/, etc), but I am wondering what all of you think about this topic. 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. Thanks for any help.
