Permission to Reply to Comments How to allow posting replies to comments to certain user roles only?
The goal is to allow users to post comments but not reply to them and have only certain roles able to post replies.

Initially I thought of hiding reply link for certain roles. But it is not a very bullet proof solution. Anyone knows of better methods?
Edit your comments.tpl.php file and delete the &lt;?php print render($content['links']) ?&gt; 

Then all you gotta do is create your own reply, edit, and delete links


reply is /comment/reply/[nid]/[cid]
edit is /comment/[cid]/edit
delete is /comment/[cid]/delete


So use PHP to load the nid and cid and replace the [tokens] with your PHP code. 

Then use PHP if statement to check whether login (global) user is of role x, if true, you print the reply link.

For edit and delete links, you check if login (global) user uid is the same as comment author uid.
