I'm wondering if this is possible... and maybe a slight "push" in the right direction.
I want to override and/or replace the default WP setting 'Blog Shows at Most x Posts' with a custom setting that shows all posts based on a date range set by the admin.
The trick is, I don't want to break the $paged variable, permalinks (.../page/2), or next_posts_link() / previous_posts_link().
Any "push" in the right direction would be most appreciated. I'm average at PHP/writing plugins.
