Participation in the Protocols and Formats Working Group

Page Contents

This page explains the requirements and procedures for becoming a participant in the Protocols and Formats Working Group (PFWG). It also explains how non-participants may contribute to the Working Group by subscribing to the group's mailing lists, monitoring the group's progress, and contributing on the lists. See also Participating in WAI for broader participation options throughout the Web Accessibility Initiative (WAI).

Join the Working Group

Participation enables you to influence the development of the deliverables, and you and your organization will be listed as contributors to the deliverables of the PFWG where appropriate. Participant status, however, requires a commitment on your behalf to support the work of the group. Participants are expected to observe the requirements of Section of the Process Document ("Good Standing in a Working Group").

Before applying to join, please read the PFWG Charter to review the activity and commitments. When you join the group, you are automatically added to the w3c-wai-pf mailing list (Member-only archives).
