The manga is licensed so, in general, full page scans and translations, or information about sites with such content, are expressly forbidden. This is your starting point, if you are unsure... start with this assumption.
However, we're not trying to stop you talking about the manga, which we understand is a visual medium and often needs visual elements to fully explain itself. So, from this assumption you can start to think about the "fair-use" concept.
Our position is roughly as
Rurik described: If the point you are trying to make cannot be made without a visual example, we are probably going to allow you to make a post containing a
partial page scan.
Partial. In other words, a crop of the page.
Provided it does not contain edits aimed at translating the content from its official print form. That is, if it was printed in Japanese, it must remain so. Likewise, if it is from the official English release of the manga, we are not worried about the speech being readable in English. What you are NOT permitted to post under any circumstances is a FAN translated version of the page. In rare cases a sensible crop (to focus on your point) might not be possible, we understand this too. If a full page is really the only way to explain your point them so be it. Such posts will probably be acceptable if kept to a minimum.
Now, if the point you are trying to make requires not visual element... then posting the image simply isn't needed. If you want to quote some of the text, then that is fine... just don't quote whole pages or chapters verbatim. The important point here is that we want to avoid the dissemination of anything that allows people to avoid the purchase of an official English release, while still promoting meaningful discussion. I think it's pretty straight forward... but if you're not sure just ask
Only... not in this thread please
