I spoke to him soon after his account went down. He deleted it.
Here is what he said when I inquired him:
"It's tough to answer why I deleted my account. It's not because of anyone on forum. I'm not sure whether I can explain it in short in a message or not."
He also said he has no grudges or grievances with anyone here.
Anyways, I love this thread.
MA was one of my favorite members here. Like you said, he was like a walking Lili encyclopedia and just so wise in general. I'd venture to say that people with his level of character and commitment are few and far between. We need more MAs in the world!
I second your message: Merci, MerciAlizee. <333
