If you want to change the local group, you need to contact* the membership system group through: member@nordmark.org *Keep in mind that it may take a while for the group to make the change as we are all working on this as volunteers. If it is urgent, it is fine to make direct contact with Nordmark's exchequer.
The member system group needs a written documentation to carry out changes in the system. Therefore, an email is required, and you cannot just talk to the person you know in the group.
