Yes, you DID respond that fast.

And your response allowed me to find the apparently undocumented plugin that gave me the hint that I had to modify parentid. But I couldn't figure out where/how to do that. MarkFL's response does exactly what I've spent days trying to figure out. It wasn't so much the SPEED of the responses that bothered me. Is MarkFL the only one who knows that trick?
It should solve the problem for future posts, but I doubt that there's any way to fix the existing misleading links.
