If you are a GNOME contributor, there is no reason why you shouldn't be part of the GNOME Foundation.
To apply for membership in the GNOME Foundation, please complete the following form in English. Your application will then be reviewed by the Foundation's Membership and Elections Committee, which will notify you when your application has been accepted or rejected.
Who is eligible for membership?
Per the GNOME Foundation's charter, any contributor to GNOME is eligible for membership. Although it is difficult to specify a precise definition, a contributor generally must have contributed to a non-trivial improvement of the GNOME Project. Contributions may be code, documentation, translations, maintenance of project-wide resources, or other non-trivial activities which benefit the GNOME Project.
Members of the GNOME Foundation receive numerous benefits, including the right to vote in elections for the Board of Directors, travel sponsorship to conferences and other events, a @gnome.org email alias, blog hosting at blogs.gnome.org and Planet GNOME syndication.
Renewing your membership
Membership in the GNOME Foundation lasts for two years. You will be contacted to renew your membership before it expires. Renewal applications are not automatically accepted. Please remember that membership's renewals shouldn't be considered a mere formality, as the Membership Committee will do the needed checks to verify applicant's contributions over the past two years.
