The Z Sustainer Program is the main mechanism by which Z is able to play its bills and operates.
A subset of our users become Sustainers, entering information and donating periodically each month, quarter, or year. Sustainers are able to post blogs, post comments, and receive nightly commentary emails.
It is hugely important, if you like the site and believe it is important not only for yourself, but for others, that you seriously consider becoming a Sustainer. Just choose the option in the left menu, and then your preferred terms. We hope you will.
