class=395464113-20042007>Folks, I've been remiss in addressing this, and I
apologize. Keith has proposed that SCPS NP, SP, and FP be transitioned to
historical status. They can be "resurrected" at any point should folks
have a need, but they have not gotten noticeable use, so the proposal is to
shelve rather than renew them. Any objections? If not, I'll launch
these resolutions under SIS cover to the CESG.</SPAN></FONT></DIV>
