The Bottings argued that such changes served the function of weeding out inactive members by periodically rendering their terminology obsolete. So that anyone who still used the word assembly for a convention for example would be instantly marked as out of step with "present truth".
So yeah I've been caught out with this latest "regional convention" change. When was it changed from district convention to regional convention and why. Did they give any rationale for the change or was it simply a change for its own sake?
