AABHL supports its members by promoting special interest groups called Streams. Space is provided on the AABHL website to allow discussion of pertinent topics under the direction of specific experts (known as Stream Leaders) in the relevant field. In addition to the Discussion Group, other activities (e.g. workshops, seminars and meetings) are encouraged. In certain circumstances financial support may be available (although this should not be assumed).

Stream leaders are responsible for the management of Stream-focused online activities and discussion, with oversight by the AABHL committee. AABHL members interested in leading a stream, are invited to write a brief proposal to AABHL providing details of

• the relevance of the Stream to AABHL,
• how they see their role as Stream Leader and what they feel they can contribute,
• how they will improve the experience of current members
• how they intend to attract new members to their particular stream (and potentially, also to AABHL).
