MyBB Community Forums

Hello ,
I am trying to edit the hello world plugin so that i can only show the hello World message in all forums except particular forums id which i enter in the plugin php file. Can anyone help me do that ?
Thanks

You mean this? https://github.com/mybb/mybb/blob/featur...o.php#L106

if(!in_array($post['fid'], array(1, 5, 7, 15))) // change the numbers to your forum ids
{
   $post['message'] = "<strong>Hello world!</strong><br /><br />{$post['message']}";
}
