Grammar Girl

A great site for middle and high school students (and not just girls!) is the Grammar Girl's Quick and Dirty Tips to Clean Up Your Writing site. Grammar Girl has podcasts explaining various grammar rules as well as including the written explanation of the rules. Although it's a bit lengthy, it's well-written and would be a great resource, especially for second-language learners. And for the super-tech twist, there is a voicemail on the sidebar that allows someone to ask a grammar question to Grammar Girl herself. I'm thinking that English teachers would appreciate this site when collaborating with the librarian or working with students who are needing extra reinforcement.
