3 Spelling and grammar is not important at all I had chance to read and still enjoyed stories that are written in a way that you need to use all your brain power do decipher what these words mean.
As long as you understand what you wrote it is OK to publish.
With all due respect, but I call bullshit on that. It might hold true for you, but in my experience most readers do not enjoy to read a story if it takes all their brainpower just to get what the writer wanted to say. There really is a reason why every publisher employs editors.
