grammar hotlines

Many colleges and universities have grammar hotlines, and you can find a listing of these, state by state, at http://www.homeworkhotline.com/GrammarHotlines.htm.  The next time a grammar question stumps you, it might be interesting to contact (or have your students contact) a few of these hotlines and see how their advice compares.  At the same website there are also links to many other websites with grammar advice, some with a specialized focus.  (spl)
