While much of the SWCHR website serves as a free online resource for guests and a limited number of our discussion forums can be accessed by free registration as a Registered Guest, we invite and encourage you to join SWCHR as Member and to become actively involved with us. The Association relies solely upon membership dues and donations to fund our operation and programs throughout the American Southwest. Our ability to achieve our stated objectives depends upon the degree of support we receive from our members and users. We have several different membership options for you to select from.
