How can I control how many posts to appear in a spesific page such as the homepage only?

dshboard->settings->reading->Blog pages show at most

But that will infect on all multipost-pages, I want to have less posts on the hompage than on other pages.

why not check out http://wordpress.org/extend/plugins/...osts-per-page/
I've never tried it, just found it with a googled search

And I have searched hours, and coold not find anything.

Thank you, it works perfect.
