It would be great if we could set the show x posts a page in x forum.
E.g. in our board there's a forum with a lot of pics and a few users would like to have displayed only 5 posts a page, and in others 15 or 20

Sounds like it would be tricky... best as a mod, I think.

I can see each forum having a drop-down list of choices, preceded by "Number of posts per topic page in this forum." So as to minimize space and confusion, this function would use cookies.
