You are proposing a bifurcation into rants and raves in one subforum and just the facts in the other.
Gotta say I'd
not be in favor or subdividing
any airline forum on this basis never mind one of the busiest as not only would it not be harder for newer members to distinguish between the two but it forces members to read both halves to gauge how or if the fact is to them a good or not so good thing which is IMHO an unnecessary duplication.
Just MHO and YMMV.
