Well, of the oldies I know well enough to hear their honest comments, they are not feeling "vigourous and fresh" as the letter puts it. Instead I hear grumbles about the Org. How they feel left behind in the techie world they have to embrace, the changed doctrines, lack of help from elders.... etc
Is this being sent to the cong? It would better sent to the old ones individually. Easily done, just get the congregation to organize it
