Oklahoma City Temple Rules have changed

Oklahoma City Oklahoma Temple
Members who want to attend the Oklahoma City Oklahoma Temple to perform proxy ordinances now have the option to either schedule an appointment or attend without an appointment, where space is available.
As priority will be given to members with appointments, those who attend without an appointment may be asked to wait for an opportunity to participate. As it has always been, appointments will still be necessary for all members who come to receive their own ordinances (endowment and sealing).
You are encouraged to attend the temple as often as your circumstances allow.
How to Reserve an Appointment
You can reserve an appointment on ChurchofJesusChrist.org, in the Member Tools app, or by calling the temple. Also, you may now schedule multiple appointments for any ordinance in any temple.
