Organic Group Forum: Private forum for a group
The organic group forum module creates a forum container for that group, with a single sub-forum. The forum can be restricted to be only seen by members of that group. Forums for group members are very useful to maintain privacy of a groups discussions as it begins to organize and accomplish the groups mission.
A category term for the group is created to tie the organic group with it's forum container.
You can:
- read about the forum module handbook page.
- read about the organic groups module handbook page.
- not administer this module.

If you, like me, have
If you, like me, have numerous subforums that should not be displayed on the main index and need to hide them, Michelle provided me with a bit of helpful code.
In og_forum.module
find:
function theme_og_forum_list($forums, $parents, $tid) {
global $user;
right after that add:
$hide_subs = TRUE;
find:
else {
$new_topics = _forum_topics_unread($forum->tid, $user->uid);
$forum->old_topics = $forum->num_topics - $new_topics;
if (!$user->uid) {
$new_topics = 0;
}
right after that add:
if($forum->depth <= 1) {
$description = '' . "\n";
} else {
if ($hide_subs) {
continue;
} else {
$description = 'depth . '">' . "\n";
}
}
I used this in conjunction with Michelle's advanced forum for great results.
