It is interesting how they "borrow" from one another.
When JWs introduced Caleb and Sophia (the children that were characters they claimed they invented) we had a thread here about an interesting development.
The development was that the Mormons had 2 young characters FIRST that the JW ones were clones of.
The thread had some posters who did a bit of digging and i I remember correctly there was some evidence presented that looked like JWs had hired the same consulting firm the Mormons had hired.
Obviously, JWs were concerned about the high rate at which they were/are losing young people. The Mormons have their own problems with that but still do better than the witnesses.
