Well...I personally still think that good grammar, which helps with the way you talk (and vice versa, so if you keep on running your mouth on in real life, you might need to take a breath every 10 seconds xD This is a joke, even if a little rude.) is a must around a writing site. The best way to get started to being a good helpful writer is to be a good writer, which of course, goes all the way back to grammar. Without grammar, it will be impossible for people to understand you.
It's good you write like how you speak, but I believe that if you used more commas and periods, it helps your readers understand you more easily, since they don't have to take in all so many words at once.
For example, I could down this sentence you wrote :
I really want to change people though cause im actually a nice person in real life and I want to try and make others just maybe more nicer in what they say and try to give new comers like me and other new comers more advice into making their stories better.
Into this :
I really want to change people though, cause I'm actually a nice person in real life. I want to try and make other just maybe nicer in what they say and do, and try to give other newcomers like me more advice for their stories.
^See how I cut the sentence into easier-to-read pieces? That's the power of periods and commas. I recommend you use them a lot (you sound smarter that way too!). Also...
...yeah, I'm going to have to tell you again that you're going to want to be a good writer before you start giving advice. It helps when you don't have a wooden pole of ugly grammar in your eye when taking out splinters of bad grammar here and there in other people's eyes.
