So, other than this suggestion, what's the difference? I'm super slow today!
How I see it:
In terms of editing, Basic and Classic are the same. Classic has just been renamed.
In other terms, the Basic editing definition has some extra details, such as the suggestion for comments on 1,2,3 votes, the details about Request for Proof, and maybe some other small stuff. However, the actual rules as to what you can and cant edit are the same.
As mentioned earlier: Classic is what all the old challenges used. Basic is what the current and future open challenges will use.
I think I understand or should that be I am sorry I asked!
However, I am glad I am not the only one that was confused enough to wonder hence the reason I started the thread.
I think I will have to print the pages and read them with a highlighter pen to hand.
But "basically" the Basic or Classic is the very limited editing only while the advanced is 'almost' anything can be done subject to any qualifying extra rules. Oh, my head hurts - just have print that one out as well.
NeatImage is specifically allowed, but if you use it to an extreme for "artistic effect" as opposed to enhancing the photo-realism of the shot most folks (here) won't like it.
