You want to contact list owners
The list owners and moderators' names are mentioned in the left menu. However, you should never write directly to a list owner or moderator: first, the person to whom you are writing might be absent, and furthermore, it is better to inform all owners and moderators of your request. When you have a question or remark, the address you should write to is: nameofthelist-request@lists-dev.btaa.org (replace 'nameofthelist' by the name of the list).
