As a registered site user, you will be able to take part in shaping the OFX standard by commenting on proposed standard changes. Registration is moderated; you will not have full access to user-accessible information until your sign-up has been confirmed by an administrator.
Membership in the OFX Association is open to companies implementing or interested in promoting and extending the OpenFX standard. The membership fee is currently £500/year (~600€, ~$800). New corporate members are generally admitted at the annual meeting, in April of each year. If you wish to join, please contact the Association using our contact form.
NOTE: You do not need to be an Association member to implement the standard either as a host or as a plug-in; it is completely open source and open to all.
