Editing your post is ideal. It's far better to do that than double posting.
It was basically a rather poor choice of words and grammar. I assumed what he was trying to say that he had edited something that Epimetheus had made. Thus I specified that permissions were necessary.
It wasn't before I saw the first post that I realized what he meant. I generally just view the description and then check out the model. I'm not used to being forced to go through the comments as well to get the full picture.
The reason is fairly simple though, the comments generally tends to be populated by comments saying "1 million out of 10" and stuff like that, with little to no value. People that give max ratings no matter what resource they look at, loses their credibility and thus their value.
I generally vould've phrased it as "Epimetheus helped me by editing and improving my older model. Please look at images below to see the old versions"
You can attach pictures to the description though, you know that, right?
