Option to set # of post per page?

Is there an option in the preferences to increase the # of posts viewed per page. For example in vB, the limit extends to 40 post per page.

Thanks again for bearing with me and my basic questions as I get my used to using Xenforo.

It's configurable in the ACP as a board wide setting.
Thanks Brogran, I understand. Can this be configured on register user end here at XF? I dislike having to click from page to page, when I can instead (if possibile) read several posts at a time just by scrolling down the page.
