The ASRG has several subgroups, some more active than others.
Currently, the Abuse Reporting and Filtering groups are fairly active.
Identity, Authentication, and Reputation has many members but surprisingly
little activity.
Since the ASRG is a research group, it looks at areas not yet
well enough defined for IETF standardization, and at experiments and
measurement about existing or emerging standards.
Anyone is welcome to participate by applying to subgroup leaders to join
the subsgroup mailing lists.
