Individuals who are employed by a W3C Member should contact their organization's Advisory Committee Representative about participation in a group. Note that for most W3C groups (except the TAG, for example), when you are an employee of a W3C Member, you are considered to represent the Member in a group, in particular with respect to any W3C Patent Policy obligations.
Some individuals who are not employed by a W3C Member may participate as an "invited expert" in a Working or Interest Group but in the general case, such participation is subject to approval by the group Chair and Team contact.
Yes. Participation in any Working Group is open to any W3C Member; this is one of the benefits of Membership.
The number of participants you may have in a group is determined by the group charter and your organization's own resource limits. The W3C Process itself imposes no limit.
The charter states the participation expectations. For many groups, participation means attending a weekly teleconference, attending face-to-face meetings in various locations several times per year, attending the Technical Plenary week (once per year), and following mailing list discussion. W3C welcomes participants to help in editing Recommendation Track documents. The Process Document includes more information about group participation.
Yes. Please see the Positive Work Environment Task Force's Statement of Principles.
