Information for Potential Members

CA/Browser Forum Membership

The CA/Browser Forum engages in discussions at a plenary as well as a working group level.

  • Members may propose by ballot the appointment of Working Groups open to participation by Members and Interested Parties. The ballot shall outline the scope of the Working Group’s activities, including deliverables, any limitations, and Working Group expiration date. Upon approval of the Working Group, the Chair will call for a show of interest in participation by Members, and shall appoint a Working Group Chair from among the interested Members. Upon creation of a Working Group, the Forum will post an invitation to all Interested Parties to participate, and will solicit others with expertise and interest in the Working Group subject matter to become Interested Parties and participate in the Working Group. With the approval of the Chair, Working Groups may establish separate list-servs, wikis, and web pages for their communications, but all such separate list-servs must be managed in the same fashion as the Public Mail List.
  • Working Groups may meet by teleconference or face-to-face meetings upon approval by the Chair and the Working Group Chair, but the Forum shall not be responsible for the expenses of any such teleconferences or meetings. Working Groups may draft recommendations to be forwarded to the Forum for its consideration, but no recommendations will be considered the product of the Working Group unless approved by two-thirds of all Working Group members who vote on the recommendations. All substantial initial and final drafts of the Working Group product will be posted on the Public Mail List.
  • The Forum shall review the final recommendations from a Working Group and may approve and implement some or all of the recommendations as appropriate in the Forum’s judgment following the Forum’s regular voting rules. The Forum shall retain the right to amend a Working Group recommendation before approval, but in most cases should first return the proposed amended recommendation to the Working Group for its review and response before voting. The Forum shall not be required to submit any matter to a Working Group, but may itself draft requirements and guidelines without a Working Group in its discretion.
