First, Take a survey how you rate my grammar/spelling.
If you vote Great or Good, how do you actually understand me.
If you vote Bad or Poor, Explain why I have bad/poor grammar and how should I improve on it. Please, I don't want people talking about my poor grammar/spelling. This is the only thread that you can say about me.
I voted "bad". I can kind of make out what you're saying but it takes a lot of effort. I will try my best to give you a short lesson now:
"First, Take a survey how you rate my grammar/spelling."
1) The "t" in "take" does not need to be capitalised.
2) We are not the ones taking the survey, you are. You should say "First, take
this survey..."
3) You haven't told us that this survey is
about your spelling and grammar, you have only said there is a survey, then the rest of the sentence is incoherent. you should say "... survey
on how...
The final product should look like this:
"First, take this survey on how you rate my grammar/spelling."
"If you vote Great or Good, how do you actually understand me."
1) You have already told us to take the survey and you can expect that we have already done so, therefore you need to use the past tense of "vote", namely, "voted".
2) You are quoting your own options for the survey, therefore you have to put quote marks around the options, namely, "Great" and "Good".
3) This part is very difficult, but my best interpretation is that you are asking for an explanation as to how it is that we can understand you, therefore you need to say "please explain how it is that you can actually ..." I am doing a considerable amount of interpretation here though so I might have missed your point.
4) I don't think there is any need for the "actually". It seems to be unecessary to the substance of the sencence.
The final product should look like this:
"If you voted "Great" or "Good", please explain how it is that you can understand me."
I still don't think this sentence makes any sense though.
"If you vote Bad or Poor, Explain why I have bad/poor grammar and how should I improve on it."
1) Points 1) and 2) from before.
2) "Explain" does not need to be capitalised.
3) You're asking for help, so use your manners; say "please".
4) I think it makes more sense to say "how I
could improve". We have already established that you
should improve on it; now we need to know how.
The final product should look like this:
"If you voted "Bad" or "Poor", please explain why I have bad/poor grammar and how I could improve on it."
"Please, I don't want people talking about my poor grammar/spelling."
I guess this sentence is fine, although you shouldn't use the word "poor", when you have not yet established that it is poor; this is the point of the survey.
The final product should look like this:
"Please, I don't want people talking about my grammar/spelling."
"This is the only thread that you can say about me."
My best guess for this sentence is "This is the last thread in which I want people mentioning my bad grammar/spelling". I have no idea how to break this up into points, it's just a mess.
As far as I can remember, this is the most help I have ever tried to give anybody on these forums ever, so you better appreciate it.
EDIT: I should add that the best advice you can take is Shelley's. If you want to learn to write I strongly recommend reading a lot. Even so that may not help; I was always big on reading but it wasn't until I started in university that I was able to write well. Even now I have to go over and over what I say to make sure it is perfect. Just take your time when you are writing a post and go over it before you post it. Say it out loud if you have to; if you can speak coherently then just type it up the same way you would say it. It should be obvious to you when something doesn't sound right if you say it out loud.
