Last December I wrote Simon lamenting the discontinuation of Cooltone developer and mentioning my quest for something that would neutralize the color of MGWT FB paper. He replied that he was seeking permission from the board to release Cooltone's formula. Twenty five minutes ago, I posted an update

detailing my testing and decision to use Moersch SE6 developer. Then, 5 minutes ago, I emailed Simon with that link, wishing him good luck with the board in obtaining permission to release the formula. I should have cruised this forum first! Thanks, Simon, for exploring the possibility of special runs of Cooltone. Additional developer options are always welcome, especially for a paper as wonderful as MGWT FB.
