no new replies are allowed, but topics are

Is it possible to create forum where users could only write new topics, but no reply would be possible on this topics. I just want to let people tell the story, but no one would be allowed to reply to this. Registration is not neccecary here, guest can create new topics also.
Thank you

Try to paste this snippet in bb_plugins.php:

/* forbid posting replies */
if($action=='vthread' and !($user_id==1 or $isMod==1)) {
if(!in_array($forum, $roForums)) $roForums[]=$forum;
}
if($action=='pthread' and !($user_id==1 or $isMod==1)) die('Access denied');
/* forbid posting replies */

Tnx, this works great. I only forgot to mention, that i would like to have only one forum with this settings.

Is this possible? Tnx

Edit:
Tnx for changing topic name to something that makes sense

So the code will be...

/* forbid posting replies */
if($action=='vthread' and !($user_id==1 or $isMod==1) and $forum=='FORUM_ID') {
if(!in_array($forum, $roForums)) $roForums[]=$forum;
}
if($action=='pthread' and !($user_id==1 or $isMod==1) and $forum=='FORUM_ID') die('Access denied');
/* forbid posting replies */

substitute your own FORUM_ID here.

Tnx..works excellent.
