Yes.  MD is evil* (and by MD, I don't mean Mike Dean).

Didn't know that was on the wiki.  I clicked reply on this message with 
the intent of linking to Chris's post on the list (that's quited on that 
page).

No.  Settings are /values/ within the DB (specifically the settings

specific settings you need don't exist in a normal system.  They're 
"undocumented" extra settings.
