Well, I guess since we were talking about a singular entry for correction, I guess I wrongly assumed that when you said “a” you were referring to one singular website, and not a subcategory of nouns that would of course make your corrections faultless, while still sounding silly.
If their is correct, then I guess my personal preference would be not to add the “a” to a “count” noun.
My bad.
Okay, that does it. I was wrong.
