My golden age was from 2010 when I first joined until the first ABL forum started and everyone left to post there.
Everyone left to post there, eh? In terms of traffic, they maxed out at 1/3 of CathInfo's traffic, at least in terms of how many registered members checked in within a 24-hour period. But none of the successors to the original ABL forum got even 1/20th of that popularity or traffic.
I did think it was funny, though, that the original ABL forum had 3 moderators, and at least 2 of them were sedevacantist. I guess I didn't know +ABL was a sedevacantist...hahaha (note: I'm joking. +ABL was not sedevacantist. That's my point: The forum was ironically named.)
