Is there a place or way, we could get an area to add the data for sourcing of our edits too when changes are being made?

Even a tiny off the side box that allows for putting (Back Cover, or linking to the artist website, a specific twitter comment)

This I think would help to keep most of the data easily accessible. Rather than a forum post. Assuming someone looks at the change log 2 years later, they would then have to look at the forums post to see why there was a change if someone decided to post it. Rather than just seeing the change and a small area to the side of it showing the link to the image scan, the twitter post (archived or not), website, etc.
