These discussions seem to come up every year, around this time. Summer activities seem to preclude participation in the Forums.
This year seems to be extreme, though. The reason could be a growing frustration with using RCU, and it's continuing user related issues.
As can be seen by looking at the join dates of the previous contributors to this thread, many of the "old timers" are still hanging around.
Let's hope that forum participation grows in the future. RCU has played a major role in my development as a modeler. I'm sure that I am not the only one who can say that.
