Well, he was on this site this morning so he ain't dead.
I guess if he wants to post he can and will, and if hes quiting and wants to say why, he can, and will.
He's definitely tolerant, and thick skinned, so I don't think he takes any of us seriously enough to get his feelings hurt.
Me and him have agreed on topics, and disagreed on topics, and he no doubt is more open minded than me.
Maybe he needs a break, or just wants to hang out with a better class of people.
