Ive never been the best at grammar and spelling, but the auto spell check has actually helped me improve my spelling. I type it the way I think it is then I see the way it should be. Over time when I keep getting corrected I remember the correct spelling.
I believe it isn't the texting and such, just the belief that it is ok to use bad grammar. I'll text in the traditional scenes of the word, but when it comes to emails and forums, I use proper grammar.
the autocorrect made it so I cannot spell becuase , it always auto corrects it to "because" and I have become very accustomed to typing it as becuase. But if it works for you, it works for you!
I try to use proper grammer, but I have come to the point where I really don't care so I don't put extra effort into it.
