 ### Members Council
 
-The Open Modeling Foundation Members Council represents formally constituted organizations composed of or representing an active community of modelers in the social and natural sciences. Formally constituted organizations should have an accessible, documented governance structure. Examples of such organizations include scientific networks, professional societies, research institutes, national laboratories, other government agencies, research centers or laboratories recognized by academic institutions, or commercial enterprises. Any such organization can be nominated for membership in the OMF or self-nominate. Any organization seeking membership in the OMF MC, **must agree to support the mission, goals, ethics, and values of the OMF**, as described in this charter and the OMF values statement, to promote OMF approved standards, and to provide professional recognition to researchers engaged in standards-based modeling. Nominations for membership will be evaluated by the Executive Committee and presented to the Membership Council for approval by a majority of the Council.

 #### Joining and Leaving the Members Council
 
-Qualifying organizations may request to become a memeber of the Open Modeling Foundation and join the Members Council by addressing a letter of request to the Executive Committee. The Executive Committee will review the request and decide whether or not to refer the request to the Members Council for final approval. If a majority of the Member Council votes to approve the request, the organization becomes a member of the Open Modeling Foundation and can send a voting representative to the Members Council.

 Every five years, each member organization in good standing must reaffirm in writing its intent to remain a member of the Open Modeling Foundation. This written affirmation of intent to remain a member in good standing should be addressed to the Executive Committee.

 An organization can leave the Open Modeling Foundation by addressing a letter to the Executive Committee expressing its intent to leave the OMF, specifying the effective date of leaving. An organization can be suspended or permanently removed from the Open Modeling Foundation if it is found to engage in illegal or unethical practice, violates the [Open Modeling Foundation Values]({{< relref "/about/values" >}}), or becomes inactive by failing to participate in Members Council meetings for two consecutive years, without excused absence. A request to consider removing a member organization can be made by a minimum of 10% of the Members Council in the form of a letter to the Executive Committee. The Executive Committee will review the request, compile relevant information from all parties, and refer the matter to a vote of the Members Council with a recommendation to approve or deny the request. A vote of 2/3 of the representatives to the Members Council is needed to remove an organization from the Opening Model Foundation. If the Members Council votes to remove an organization from the Open Modeling Foundation, removal is effective immediately. There is no appeal to this vote of removal. However, after a period of not less than one year, an organization can request to rejoin the Open Modeling Foundation. Such a request will be considered like any new request to join the Open Modeling Foundation.
