Couldn't care less for the immaturity

Correcting spelling is immature? You need to step into reality.

Its the internet, i only make an effort on spelling in the real world

You're a mod and you only try spelling things properly in the real world? Seems unusual to me. Grammar/Punctuation/All that is the first step to success Just because we're the internet doesn't make us less important.
Also, useful thread But if someone's getting optifine, they could look on the website and find those instructions That way they don't have to open a new tab/different website.
