Grammar bytes, aka Chomp Chomp, is one of my favorite grammar sites. The grammar explained is traditional, but the presentations and examples are clear and effective. Plus the site is friendly without being jaunty. I hate jaunty.
My only complaint about Grammar bytes is the loud, sudden, and delayed chomping sound that startles me out of my wits every time I hear it. Those of you with outsized startle responses, consider yourselves warned.
Robin Simmons, the creator of the site, is offering a MOOC starting Wednesday September 18.
I'm signing up.
