TBers, 

I am sometimes asked by faculty or students, "how good are computers at checking grammar?"   Well if they were really good, you'd never see a grammar error in my posts!!  Still, there are grammar checking services that are getting "pretty good."  Here is the latest of them, thank to Dr. Mohammad for passing this along to me.  I also posted a recent review of this service.
