With WordPerfect you can write in Canadian English without issue. So I am. Because I am Canadian. This is the first time I am doing so because other programs were so frustrating in how they were set up. One would keep changing back to US English. One would not spellcheck in Canadian English. Fine, I said at the time, US English it is.
And you know what? I now know my US English pretty damn good. So good more than once today I spelled some simple words wrong due to spelling them the American way and not the Canadian way.
It think it might take some time to get the hang of my Canadian!
