Brian, Any profiles you have added on your part of the Wikitree might be useful for other members in the future. As others connect up to them they may also be able to add new information which could be useful for you. Have you considered keeping your account open? There is no requirement to contribute regularly, so you would be able to see any additions to the profiles you have added and have the information readily available if you change your mind at some stage in the future and decide that Wikitree could be worth another try.
