Good grammar website

If you have any questions about grammar, or you're just interested to learn more about it, here's a website you should definitely check out.

The Guide to Grammar and Writing - http://grammar.ccc.commnet.edu/grammar/

Designed and written by Professor Charles Darling of the Capital Community College in Hartford, Connecticut, this huge site covers just about every aspect of grammar and writing you could want to know about. The 'Word and Sentence Level' section alone comprises pretty much an entire in-depth course on English grammar. The site also includes some of the best self-study tests and quizzes I have seen on the net, all with instant feedback.

There is also a free 'Ask Grammar' service for any grammar-related questions you may have. Check out the huge questions archive first, though, as it is quite likely that someone has asked your question before! Unfortunately Professor Darling has been unwell recently, but according to the site he is making a good recovery, so I'd like to wish him a speedy return to full fitness.
