Dear Felix
I will consider it a great honor to serve as honorary chairperson and to grant permission to your organization to use my name for promotional purposes. Prior commitments, however, dictate that I must participate in name only. Nevertheless, I am immensely interested in your progress and would appreciate you sending me literature for each goal you undertake.
May your endeavors be successful. Our community stands to benefit a great deal as you accomplish each objective.
Regards
Lydia
