CMS How to remove this line from CMS articles that have been promoted from forum posts?
 

Currently we're using the "Promote to article" feature as a way to post articles under a members username since we cannot choose a username when posting an article. We just pick a random post by the user, and "Promote to article" and then edit it with the content of the article.

However, doing this adds a small line at the bottom that reads: "This article was originally published in forum thread:" Along with a username, thread, etc.

Is there an easy way to remove this? Since we're basically using this to get around not being able to post under a users name, we need a way to get rid of this line.

Thanks in advance!
