Use your considerable clout to fix the NFPA's crappy website, publish ROPs and ROCs in a readable format again, and you might find as many proposals to read as previous cycles - might even be some good ones out there.

Considering the comment as facetious in nature...I will say I have no more clout in that crowd as I do in this crowd and leave it at that.
