Grex is a service offered by Cyberspace Communications, Inc. In spite of the corporate sounding name, Cyberspace is a non-profit organization, staffed entirely by volunteers and doing nothing except running Grex. It is funded almost entirely by various kinds of donations from our users. Since we are a registered 501(c)3 corporation, all donations are tax-deductable.

If you want to help support Grex, you can become a member, or you can just send us some money.

You can make donations by mail by sending a check to:

Cyberspace Communications, Inc.
P.O. Box 4432
Ann Arbor, MI 48106-4432 (USA)
