Welcome back! I think TLKFAA is probably seeming less active because all of the "old guard" has pretty much evaporated. Things happen. Like life, you know? Probably most of us have jobs and/or families that consume our lives now. I think it's pretty active with a much younger crowd these days. Give them a few years, I'll bet the cycle will repeat.
So, my question, what brought you back? And why did you leave MLK?
