I think s/he means that you should put the clarification into the text of the actual class. It's more of a formatting thing -- it's easier to understand classes when the explanations of their abilities work are listed on the character sheet rather than in a separate post written a few days later, so it would be really helpful if you edited the original post with the clarification (if you haven't done that already, of course!)
For example, with the darkness aura, if the affected character has to make the saving throw once every round, you should spell that out in the description of the ability to ensure there aren't any ambiguities (ie -- are you making the save every round, or only taking the damage every round, or both?)
It's a neat ability and I personally would like it either way, but it does make a little bit of a difference how the save works.
