comma after discourse marker [necessary?]: furthermore, moreover

[andersxman]

When starting a phrase with the following discourse markers, is the comma obligatory? Or maybe there shouldn't be one at all?

For example(,)

moreover(,)

further(,)

furthermore(,)

I was taught to place a comma after all these words except "further," which is not often used as an introductory word in AE. If it's used in the same way as "furthermore," however , a comma would be appropriate.

Absolutely agree from a BE viewpoint.

Same thing goes for "thus", "hence", "therefore"?


I supposed there's a never-ending list of examples to ask, that doesn't come to mind in this instance. I reckon the answer is "yes, discourse markes are succeeded by a comma"?
