Canadian, British and American Spelling

I have another of my little pet projects under my belt. My webpage on Canadian, British and American Spelling is now live.
I have tried to explain and produce a more or less definitive listing of differences in regional spellings, which is particularly a problem in Canada because, as in most things, Canada tends to lurch and wobble between the British and American camps. There are one or two resources on the web but I didn't find them very comprehensive or definitive, so I made my own.
In addition to a detailed, searchable word list, there are additonal pages on the general rules for regional differences, a page on the basic spelling rules for English with examples and exceptions and a page of commonly misspelled words.
Several hours of poring over dictionaries, grammars and style guides in the library, as well as some serious web-surfing, have paid off I think. Let 's just hope someone actually uses it now.
