If you go into the Dancer forum, and look at the linkbar just above the forum posts (that show the subcatagory forums you went through to get to that particular forum), you see 'fjob19' as the name for the Dancer forum, and it's a subforum of "Custom Forums".
Clicking on forum=fjob19 takes me to an empty forum.
