I think there’s a bit of confusion here.
When “real israeli” said “gefen: check out the 2nd post on the AYC AYeCo thread“, I think he meant the second post on the second page of that thread, namely this one:
http://theyeshivaworld.com/coffeeroom/topic/ayc-ayeco/page/2#post-320625
That post makes it appear as if “am yisrael chai” has returned. Unfortunately, that’s an old post – since then, due to circumstances that need no repeating here, he’s left and hasn’t been back.
