The general membership of the PSI is open to all who wish to participate. Everyone is encouraged to post to the corresponding mailing list or contact any one of the leadership members of a working group to indicate interest in a specific project, and be included in the ongoing activities. Organizations that have been in operation for so long can seem closed and cliquey, but the PSI actively seeks to dissuade this notion. Individual standards or projects are not necessarily led by working group chairs, but ideally led by those who are most interested in completing a project, regardless of their status. In general, the PSI only develops standards where at least one working group participant is an active champion of the standard and drives its forward progress. Proposed or desired standards without a champion usually are not developed. However, anyone in the community with the desire to see a new or updated PSI standard is very much encouraged to become a member of the PSI and champion that project within the umbrella of the PSI.
