Fairchj left on his on accord. As he had done previously, he requested to be removed from the forum and this time Agrocom obliged. From his own post on SH the following day, he was trying to be reinstated but I suspect Agrocom is making him go through a wait period. I believe, if he could be back he would be back. Just give it time.
Rainer in no way, shape or form had anything to do with FJ leaving this board. I find Rainers posts to be extremely well thought out and without personal agenda. He (as with FJ) is obviously very knowledgeable and I always make sure to read his posts for their technical and level headed approach. Thank you Rainer.
