Guidelines for the use of Commons e-mail for soliciting donations to non-profit organizations and other causes: (1) You are personally involved in and passionate about the non-profit organization or cause for which you are soliciting. Do not use the Commons email list to solicit on behalf of non-residents causes. (2) Send only one request. It is not necessary to follow-up with multiple reminders or requests. (3) Use NC in the subject line (NC stands for Non-Commons).
