People get irritated when they are corrected...

yes and its annoting that you have a teacher that wants everyone in her class to type a different way a slower way but im not doing that so screw her

What is the slow way?

ON TOPIC: I think grammar patrol would be nice, but I just like to know when I mess up so I don't make the same mistake 115 times! There is nothing worse than trying to explain something and people look at you like you are retarded because your post looks something along the lines of, "tEh greight nad Almitey Roolz uv Zelaron!!1!1!one..." Especially when it is something helpful.

It would be useless. Most people don't care whether or not their grammar is correct, and ignore all attempts of correction.

yea, especially on online game
