[Grammar] No one replied so I separated this topic from the original thread

[kadioguy]

a. No one replied so I separated this topic from the original thread.
b. No one replied so I separate this topic from the original thread.
c. No one replied so I am separating this topic from the original thread.
d. No one replied so I have separated this topic from the original thread.

e. No one has replied so I separated this topic from the original thread.
f. No one has replied so I separate this topic from the original thread.
g. No one has replied so I am separating this topic from the original thread.
h. No one has replied so I have separated this topic from the original thread.

Which of them are possible? Could tell me the reason?

The first one is fine, but you need a comma after replied.

I might have something more to say later.

Every sentence needs a comma after "replied".

The sentences that I corrected had incorrect sequences of tenses.

Sentence B uses the present simple in a way that is not natural.

 

[Charlie Bernstein]

They're all fine but B and F.

Every sentence needs a comma after "replied".

But I found that sometimes there is no comma before 'so'. For example:

[Matthew Wai]

Some consider it obligatory, while some consider it optional.
This learner always puts a comma before the conjunction 'so'.

 

[bubbha]

I prefer using a comma in these cases, but others may prefer not to.

The seven coordinating conjunctions used as connecting words at the beginning of an independent clause are 'and', 'but', 'for', 'or', 'nor', 'so', and 'yet'. When the second independent clause in a sentence begins with a coordinating conjunction, a comma is needed before the coordinating conjunction.

PS I wonder why the OP is so fond of screenshots when 'copy and paste' is so convenient.

I am fond of screenshots because they are completely what they originally are.
Besides, sometimes I have to spend time arranging bold, italic and text color if using 'copy and paste'.

 

[Matthew Wai]

Leaving aside what others think, does the OP find it clearer with the comma?

Yes, that is true! Maybe I should learn it.

PS Could you tell me why you like to use third person nouns such as this learner and the OP, instead of second person pronouns and first person pronouns such as you and I?

 

[Matthew Wai]

The reason was already stated at https://www.usingenglish.com/forum/...-Simple-Past?p=1345960&viewfull=1#post1345960

Kadioguy, I promised (sort of) that I would come back to this thread.

When I looked at the post #1 I saw eight sentences. I read the first one, then I decided that maybe later I would take a serious look at the rest of them. But there were other things to do

What would I have said? Possibly: "Nobody was responding to that one, so I decided to start a new one."

As for Matthew's comment about talking about himself in the third person, that happens occasionally as when someone refers to himself/herself as "this speaker of British English" or "this speaker of American English". However, Matthew does things a little bit differently. ;-)

One more thing. Matthew's understanding of English grammar and his ability to use grammar terminology is amazing. (I do not know one conditional from another.)

That is all.
