I know what you mean ... I've been been in Canada for the last 34 years ... British, Canadian and US English spellings start to get mixed up. Plus MS Word's spellchecker I can't seem to get rid of US version. But I have sympathy for skeptic; the problem with sceptic, it can seem awfully close to septic ... especially when one consider words like science, scene, scent and sceptre. (sceptre is showing up as a misspelt word).
But what pisses me off is people's reluctance to move to the metric system. When I go to the UK it seems to be going backwards.
