Thanks for your reply Tony.
2. "Alternatively users may decide to opt out and stay at iSpot and not migrate"
OK that makes sense for me - but the logistics of the migration becomes an issue.
How are you going to relocate part of the data to iNat? eg comments, agreements by an individual who has stayed with iSpot and not registered with iNat ?
Here meaning iSpot? If that is so, I'm happy. and really all I wanted to know.
But your messages, that appear from time to time, don't really reflect this.
