Did we used to do this grading business?
No. I take the freedom in suggesting an aid, if one is not sure about how to rate or vote. I have a different approach towards it and maybe it'll be liked; I also like experimenting. It's not a big deal, once you've got the grips of it, or so I think ;-) - you can do as you wish, it's a "can", not a "must".
And must we use the graphic as our image? Could we use it as a footer instead, or do you have a footer for us to use?
No. Use whatever picture you like and which fits the finished story, from your point of view. The graphic will be, as it seems, not further used. I am talking right now to the originator.
I am looking forward, too :D
