When submitting work to Echelon Press…
OK is Oklahoma.
It is not okay to use OK to say okay!
While it may be acceptable at other publishing houses, it is not okay at ours. Please do not tell me that O.K., OK, ok are correct according to etymology, I have read them all. I accept that. However, when the United States chose to change all the state abreviations, OK became Oklahoma, and in my opinion, that makes it incorrect when indicating that something is adequate.
That is all.
