[BUG] Anonymous people can post to Link Redirection Forums

in Integramod 1.4, If you have a forum configured as a link redirection, then any anonymous person can make a thread in that forum simply by launching the posting URL and that forum ID EVEN if the forum is visible only to registered users. All the person needs is the forum ID.
For example if your Link Redirect Forum ID is 29, an anonymous person can simply enter......
http://www.yourdomain.com/posting.php?mode=newtopic&f=29
This should be fixed as soon as possible.
