In 1.0 RC, it appears I need to have the users select the "forum" or "category" for their new post to be tied too.
However, I only have 1 forum - so in my post-form.php template, I removed the following code which produces the dropdown list (since only 1 value is selected).
<label for="forum_id">Category:
<?php bb_new_topic_forum_dropdown(); ?>
</label>
But now, when I try to add a post - I receive an error message that says "This topic has been closed".
Any idea how I can force all new post into the only forum I have setup ... so that I don't have to display the "category" dropdown menu which only has 1 item listed.
