Has anyone got anyone got any creative ways to fight back against the Microsoft linguistic orthodoxy?

One of the things that I was delighted to discover when I switched from Office 97 to Corel's WP8 was a much wider range of English variants to choose from. WordPerfect even offers Australian English as a choice, and, as that is as close to NZ English as any word-processor is ever likely to offer, I have set that as my default. Now I get pinged whenever I spell a word -ize, instead of -ise. How's that for killing two birds with one stone? Break from M$ hegemony, and get more choices as to the default language for your spell-checker
