When people complain about the lack of pages I often wonder just how often they used them. Personally, I almost never used them and four pages will be more than enough. If I want to go back further then I use the "my postings" or the search facility.
Perhaps those who want ten pages should just log on more frequently or else accept that they just might miss something.
If four pages is going to speed up things for all of us then I am in favour of fewer pages.
