If spelling matters to you then please take a little time to review www.Australian-Dictionary.com.au and see how my work can assist your written work. My work is a result of the past 11 years of producing dictionary files and as a result I've uncovered many issues in Microsoft Office, Internet Explorer and Mac OSX which is reducing the quality of your written work. Often you'll think something is a little strange but then think your software knows best. It often doesn't and as such is creating bad spelling habits you should be aware of.
Once you become aware you'll never look back.
