Track and Report on Contributions, Memberships and Event Registrations Resulting from Mailing Click-thru's

Provide a mechanism for including LINKS in Mailings to Online Contribution Pages, Membership Signup/Renwal and Event Registration Pages - such that if a mailing recipient clicks the link and completes a transaction - then the "source" mailing is recorded. This feature is designed to allow organizations to evaluate the effectiveness of their mailings relative to fund-raising, membership drives and other campaigns.

Implementation details TBD.
