Report at the link below says:
Embaressed by yor spelling? Never you mind. Fed up with his students' complete inability to spell common English correctly, a British academic has suggested it may be time to accept "variant spellings" as legitimate.
Rather than grammarians getting in a huff about "argument" being spelled "arguement" or "opportunity" as "opertunity", why not accept anything that's phonetically (fonetickly anyone?) correct as long as it can be understood?
To kickstart his proposal, Smith suggested 10 common misspellings that should immediately be accepted into the pantheon of variants, including "ignor", "occured", "thier", "truely", "speach" and "twelth" (it should be "twelfth").
Then of course there are words like "misspelt" (often spelled "mispelt"), not to mention "varient", a commonly used variant of "variant".
This all sounds good to me. I’ve been treating spelling as a “creative art” for years.
