How do you limit the number of recent posts that show up in the side block (forumposts) it is set to 5 by default...

phpblock_forum_newposts - need to edit to limit the number of posts it displays - how?

In the Forum 2.5, that's an option in the Forum's settings (from the Admins Only block). In 2.3, it's hard-coded in function phpblock_forum_newposts in the plugin's functions.inc file.
