I heard from some sources that certain Zone and Region Chairpersons who are intended to be appointed have already served in this position previously.
I had asked for confirmation from the DG Elect and a few PDG's but as usual the PDG's choose to keep mum as they will probably say it is the prerogative of the DG.
A quick check on the internet showed the following:
(2) Membership Experience
Why do members join? What do members want in their club experience?
Learn ways to keep your members satisfied and resources that can help
you achieve your goals.
If I join a club and find out that the same members are appointed more than once I will resign immediately as my chance of learning and thereby serving the Lion Movement is limited.
