I've scanned one Doujin because of the one currently on here has some missing pages. However while reviewing what is/isnt missing, their version has pages that aren't on mine either. This is for several pages and leads me to believe this is a reprint with some new content and other content removed.

How should I go about this? Upload mine and leave the other as-is? Expunge the other?

Mine is 26 pages. Theirs is 24.
I have 4 pages they dont. They have 2 (maybe 3 or 4) I don't have.
