Not the type of bloke I'd want moderating my forum.
I understand where you're coming from, because when I first joined this forum, I too, wanted them to proofread my homework and re-write my college essays, whether it's a short paragraph or two-three page paper, but they refused. I now understand why -They're here to guide us as teachers, so it'd defeat the purpose for them to do your work or change your words completely because then it becomes unauthentic.
I'm not trying to add fuel to the fire, but these guys have really helped me a lot on this forum, and if you are detailed and specific in what you need help on or what you're asking them to check, most of them would gladly lend a hand. Keep in mind, they're not getting paid to do this, and private tutors in the real world are not cheap.
