But then many ppl would pronounce [mei] and [mein], don't you think?

Not really any concern of mine, as nobody would ever spell things except with the current broken "system". Spelling reform could never work in this country or the UK.

As for my spellings, almost everybody that speaks a language that uses the Latin alphabet would have an easier time of pronouncing English words written in my system, because we are the only language that has changed the pronunciation of the cardinal vowels so much (over 600 years ago), but never bothered to update our spelling.

Ceci n'est pas un seing.
