Forum:Interwiki transclusion

On the RuneScape Wiki, a user asked how to transclude a page (his userpage to be exact) from another wiki onto our wiki. Is there a way to do this? -Evil1888 08:56, July 8, 2010 (UTC)
 * I know you can do it if the template's on central (i.e. this wiki). I do that for a cross-wiki userpage, simply put in, and it transcludes from central -- Random Time  10:55, July 8, 2010 (UTC)
