Yes, if it is used as a conjunction.
Example:
It was raining, so I stayed inside.
Here, "so" connects two complete sentences, so you use a comma.
However, you do not always put a comma in front of "so".
Example:
One of my classes today was so boring.
Here, "so" is used as an adjective. Therefore, you do not need a comma.
A sentence splice (alternately, comma splice) is when 2 independent clauses are joined by a comma. This is not grammatically correct. To fix a sentence splice, you can either change the comma to a semicolon, or you can add a coordinating conjunction after the comma (for, and, nor, but, or, yet, so).
No comma is necessary before "Jr.", "Sr.", and the like. No comma has ever been necessary before "III", "IV", etc. From the Chicago Manual of Style (http://ow.ly/gcv0):But please note that within text, if you decide to use the more traditional comma before Jr. or Sr., the function of the comma is to set off these abbreviations, so an additional comma is needed after the abbreviation if the sentence continues (as in my first sentence above).
put in a conjunction (and, but, yet, so, for, or, ) and comma, make it into 2 sentences, or add in a semi-colon
The time on the east coast is three hours ahead of the west coast, two hours ahead of mountain time, where I am, 1 hour ahead of central time. so where ever you are, then just add 1,2,or 3 hours to your time, and that is the east coast time!
A comma typically goes before "so" when it is used at the beginning of a sentence to indicate a reason or result. However, when "so" is used as a conjunction in the middle of a sentence, it does not usually need a comma before it.
If "so" is used as a coordinatingconjunction, the comma goes before it. Example: Martha is really sick, so she is going to see a doctor.If "so" is used as an adverb, no comma is needed. Example: He is so very happy.
You can use a comma after an opener , so if it is 'Finally' the opener you are talking about, then yes.
Yes. "If he says so, we do so."

Only proper nouns and I are capitalized after a comma. But is a conjunction, so no, it doesn't need to be capitalized.
Typically, a comma is not used immediately after "though" in a sentence. However, if "though" is used as a conjunction at the beginning of a sentence to introduce a contrasting idea, a comma may be used after it.
Use a comma + a little conjunction (and, but, for, nor, yet, or, so) to connect two independent clauses, as in "He hit the ball well, but he ran toward third base."Contending that the coordinating conjunction is adequate separation, some writers will leave out the comma in a sentence with short, balanced independent clauses (such as we see in the example just given). If there is ever any doubt, however, use the comma, as it is always correct in this situation.
