should add a description about how the series is already licensed so that people stop asking where the chapters are.
That doesn't matter as much as you make it sound. The reason this stopped being scanlated is due to a lack of interest from any other groups since it got dropped, not whether it's licensed or not (granted, being licensed can be a factor for groups deciding what they might want to work on or not, it's still not the only one is my point). One Piece is still being scanlated by
two separate groups. Right alongside the official chapter releases being free to read in English for a while. The only reason those groups versions of the chapter aren't on here, is because those groups both don't use this site and don't allow their chapters to get uploaded here by others.
Now, the reason other sites do have many more chapters of this on them than we have here? That'd be because everything from chapter 20 up is a scan of that officially licensed release and those aren't allowed on here unless the license has gone the way of the dodo. But they are out there if you're a cheap bastard for any particular reason (personally, I'd prefer to read the entire thing before I slap it in my already quite long backlog of "series I would like to buy when I can actually afford to do so," I think I still have a few volumes of Jormungand to grab before I move down to the next one in that list).
