Ha, THANK YOU!

Like I said, I can only really imagine a writing-prompt-type scenario, otherwise it's... yeah. I don't get why you would want to use one beyond that. Maybe to see examples? Some people might do that, I guess. But they're going to be in the minority, let's be honest.

Overall, they're like those 'essay writing' services - it's not your work, and if the examiner finds out you used one, you're gonna get a big fat zero.

And thank you so much! :)
