xenforo by default doesn't come with the ability for users to control how many posts they can view per page. however, after researching it, it is implementable, and i believe we should implement it. there's a lot of benefits of doing this. off the top of my head, if you're searching for something specific in a certain thread, instead of clicking each page and performing a search, you can just have all the posts on one page and search. it makes the forum more customizable.. it's just nice.
