This will affect all forums:

global $bb_roles;

$bb_roles->remove_cap('member','write_topics');

$bb_roles->remove_cap('member','write_posts');

You can put it into header.php or make a real plugin ie.

members-cannot-post.php (and install into /my-plugins/)

<?php

/*

Plugin Name: Members Cannot Post

*/

global $bb_roles;

$bb_roles->remove_cap('member','write_topics');

$bb_roles->remove_cap('member','write_posts');

?>

I think I will make a real plugin which can control this on a per-forum basis since this seems to be a requested feature that is not too hard to handle in 0.9 Look for it in the plugin section over the next day or two.
