In the example from the title, is it mandatory to use that?  The original sentence I picked up was from a checkbox marked     Confirm you are not a spammer   which I thought should be     Confirm that you are not a spammer   though I have seen a lot of usage without that after searching around.

Consider the following use case:   Please check the username and password are correct. Please check that the username and password are correct.   In this case, I would say that that is required because it feels more natural to me and so the flow is better. However, is the lack of that wrong in this case?  The question boils down to: when is that optional? See . A quick summary:   That is optional if the pronoun is the object. That is required if the pronoun is the subject.   I think that we fall into the second case: that is required because the relative pronoun is the subject. But I'm not sure if I'm interpreting these rules correctly. Can someone please advise?

I see people putting these in emails, are they correct? My gut feeling says that please would have sounded a lot better.     Do let us know your thoughts.   Do let me know.   Do consider the proposal.

I have some doubts about the usages of That and Who. Sometimes I read sentences such as. "You are someone I love" "You are someone WHO I love" Or "People were asked to describe the qualities they look for in a friend" "People were asked to describe the qualities THAT they look for in a friend"  Why in some of these sentences WHO or THAT are omitted and others are not. Could somebody help me with this? I'll appreciate it! Thanks a million.

I remember there was a thread here on English.SE this month where someone explained this, but I can't remember how it was called. An example:     Where have you stolen this product?   This question implies that you've stolen this product, although I don't know for a fact you really did.

Tests are hard to solve for large number of users.   Checking the similar usage of such expression, I think there is something wrong with the sentence. What's the best and correct? a large number OR large numbers OR even something else!

First this question is related but definitely not the same as this very nice question:    I want to understand something: when I do '&amp;', I'm forking right?  Is it ever useful to do "nohup ... &amp;" or is simply &amp; sufficient?  Could someone show a case where you'd be using '&amp;' and still would want to use 'nohup'?

on the internet I read the following explanation: "we aren't using "no" to agree, we are using "no" to CONFIRM the negative statement."  Does that mean you confirm a negative question with no and agree with yes? That somehow seems strange to me?

I encountered this sentence when I was learning another language. I have never used such a sentence in English nor seen one, but it seems it exists.  What idea does this sentence trying to convey? What time should we relate to?

From :     [...] in early parts of this century when it was the most user- and hardware-friendly Linux operating system available [...]   Is the user- fragment valid (outside this technical/informal context)?  The usage in this context is clear, as it's just avoiding the repetition of -friendly, but is it correct?  Would it be more correct to omit the hyphen?

What is the etiquette to denote the end of an example or remark? For proofs, it's the QED symbol (white box). I know it's not necessary for everyone, but I would like to use it to break up the text a little. What should I use? A circle or filled box or what?

It's    that posting links to your own website is ok, but should there be a line drawn? There were several spam flags today for 's recent posts, presumably because they all link to his website. Initially I disagreed because his answers seem for the most part relevant to the question, but then I looked into it more and realized there's three things that set this apart from most of the related cases that have come up:   This isn't an occasional thing -- he's posted  in the last year This isn't a random blog he writes for a fun, it's a for-profit company he  and makes money promoting I'm not willing to go through all 412, but from the sample I checked, he generally doesn't mention that the products he's recommending are his own. The site is linked from his profile, but most people aren't going to check that   Is all this considered acceptable use, or are the spam flags accurate?

I'm a bit confused about this. Which expression is correct?     You can't just do that.    or      You just can't do that.   I'm trying to say:     You can't just bash an ideology because of what someone has said/done.

I want to describe my business and want to refer to it in a sentence.  I am trying to say:      "In 2015 we established a business (that is) named X".   Intuitively, the "that is" part is redundant, and makes the sentence more cumbersome. But I cannot think of a reason why we should be able to drop the verb.  Is the version without the "that is" part grammatically correct? How can it be explained?

Is this sentence a question or a statement (or other). It ends with a question, so I used a question mark. (Just ignore the tech jargon.)     I get that this should show me the PID of the SIGTERMing process and I successfully   compiled it, but how do I use it?   Edit: Another question, should it be written as (which is correct and which is clearer?)     I get that this should show me the PID of the SIGTERMing process and successfully   compiled it, but how do I use it?

For example, I found the following sentence written by a native English speaker (UK) so I'm going to assume that he knows how to put it the right way, although I wouldn't use this form.     I now have a bit more time to fix bugs   etc but I'm open to offers if anyone   wants to help maintain this module   with me?   Is it correct or is the question mark misused here?
