One of the basic things aclub administrator has to do is to keep the database updated
This includes not only to add new members and delete leaving members but also keep the figures updated, mostly adresses and e-maillinks do often change.
Each district and nation has his own system, so it is up to them to coordinate that.
Do not refer to one of our staff members in Ghent to correct data figures, it is your job or the job from the person in charge in your club
