Daryk,
At this point, the Admin team have decided to keep the existing structure in place, which means the Hall remains under Roleplaying.
While well used by a significant group of members, it's not used by as wide a group as forums like General Discussion or Off Topic. So keeping it as a sub-board makes sense from that perspective.
Sorry that it might not be the outcome you were hoping for, but we've got to manage the forums for all groups. (Otherwise, if I had my way, they'd all be sub-forums off the Minis forum ;) )
Worktroll, Administrator.
