First you have to quit your current club. You can do this from the CC home page, by clicking the "Quit Country Club" button on the page. It should be located under the "Club Forum" tab of the page, as shown below:
Once you have done that simply request membership in what ever CC you would like to join. Hope this helps you.
If you have not decided on a new club yet, feel free to check out our website for more information on the JMCC.
