I agree with all of these notes. Premium questions do receive quicker attention as noted, but #8 makes an important distinction that these members can also access eNotes resources without limitation. They can also ask as many questions as they wish. I am comforted in this: if a student asks a question that is not clear and I respond literally to what I see and it's not what they want, I feel better that they can ask again, making a clearer note of what they really want.
I find it interesting, though I have not noticed if it's still happening of late, that the red "e" next to editor's names don't always show up, so if someone has answered a question in the "pool," I have to read the summary to see if it's an editor and see if I can answer the question that may have a response by a student.
Another concern is that questions answered by other editors are still showing up in the pool. I'd feel more comfortable if once they are completely answered, they just went away: then I wouldn't feel so bad about missing a great question because I wouldn't be repeatedly reminded by seeing it still there. :)
