I'm new to Mumsnet and still trying to figure things out here. When I go to customize, the maximum amount of posts I am allowed to show per page of a thread is 100. I would like to be able to search threads on one page, so would like to have the maximum number of posts available showing. Apparently other people set things to see 1000 posts on a page, I'm wondering why I can't?
Also, is it not possible to edit posts when you realise you've made a mistake just after pressing send?
