I think I understand - With Ronan's death, there are not many alive now, who worked for Caroline at it's birth in the sixties - Rosko, being the only exception, who is helping out. There are others, but they seem to be keeping their heads down.
Perhaps they think helping Caroline, might endanger their current employment?

I'm just very pleased that enough chaps & ladies, both in front & more important, behind the scenes - give their time & talents, to keeping the Ross, the internet & broadcast side - working.
Will this all still be happening in another 10 years, I ask?
