On joining ALMA, members nominate their chosen level of privacy:
Details can be made available only to the ALMA committee and shall be used only so that ALMA can forward information.
Details can be made available to all members of ALMA but not to any non-members.
Details can be made available to anyone at the discretion of the committee.
Members nominating level 2 or 3 will be placed on a mailing list, which is available to ALMA members.
Members nominating level 3 may be placed on referral lists and other generally public lists though ALMA usually seeks consent before doing so.
