Edmonton teacher, Wade Hutchinson, told me last week about Bootstrap Grammar. The purpose of the site is to provide simple, illustrative examples to help folks avoid common errors in writing. Jean Samis, a BC teacher, who will provide for the asking, some test materials. The 77 page pdf is free to download and use by anyone.
