If the comments under renders would be interesting constructive and informative, than it would be nice to keep them visible for all.

But mostly! mostly! they're not. So I find that idea, that the comments are visible just for the creator of the render very interesting and

I've really never thought about that possibility. I think it's at least worth a try.

After reading some of the comments here I get the impression that some comments were missing.

Something which is written looks like a reaction to something which is not there.

If this is the case, it would be nice if there would be some information about a deleted post and perhaps the reason of the deletion,

otherwise it is very confusing for someone like me who entered the discussion lately.

Sorry if this was not the case and I simple didn't understand something right.
