Forum:How do I put something already written in a new topic in a forum?

When we create a new topic here at Wikia, has been written:

How I do, in my wiki, to put something like that when someone creates a new topic? I use the MonoBook theme. 09:17, April 11, 2010 (UTC)


 * The index page of your forums needs to have a createbox (a field to input a new topic), and there needs to be a template (assuming you already have one called Template:Forumheader).
 * First thing you need is a createbox that is set to include the template every time you load a new forum. On Central, the createbox is coded:

break=no prefix=Forum: preload=Template:Forumheader/ buttonlabel=Add new topic width=50
 * (Make sure you have a line called "preload".)
 * Then note Template:Forumheader/Community Central Forum. Say for example you have your forum creation box on a forum called "Index". You create a template called "Template:Forumheader/Index", and put whatever you want to users to see on a new forum on it. That should be it. The 888th Avatar   (talk)  11:02, April 11, 2010 (UTC)
