Urahara chapter 1 [English], + the Complete Japanese manga (230 pictures), by Bareisho

It really depends on which of Oliver's Japanese shares you are talking about. Some of them, like this one, are already being worked on by someone who is doing it for free. In other cases, the book is a donor project that requires people to chip in money if they want to see more of the book translated. Finally, there are a couple tanks where no one is currently working on translating any of the remaining chapters.

So depending on the book, you have a few options: If it is currently something someone is doing for free, why not stop by their website and thank them directly? It might encourage them to work on the chapters faster. If the book is a donor project somewhere, go to that site and thank the donors, and consider chipping in some money to help. Even if you can't afford to chip in, simply thanking the donors can help to encourage them to fund more. Lastly, if the book is not currently a project anywhere, you can try to get it started yourself; many of the free translation sites have a place where you can make suggestions for projects you would like them to do, or you can contact a translator who accepts donor projects and pay to get the tank started as a project that others can then help pay for.
