The Alliance is approaching a transition in which it will change from an informal collaboration spear-headed by a small group of founding members1 into a formal trade association. This change is scheduled to be completed by mid-summer of 2012. After that time, Observer memberships in their current form will no longer exist. However a variety of new options for participation and membership in the Alliance will be offered.

Please review the benefits enjoyed by members of the OCA Alliance, and contact us with any questions.

We look forward to working with you!
