CAP is not removing signatures at all. Affiliates can edit and maintain signatures as normal.
In an effort to provide greater tracking and measurement of which affiliates join certain programs through CAP, we require an affiliate manager who represents a listed program to simply contact us to make an edit to the default signature which will provide a link for affiliates to join should they wish. At the end of the day, we provide a service and would like our results to be monitored and tracked if we are held accountable to them.
We apologize for not communicating this change in advance. If any other program manager has a question, please contact us and we will gladly clarify. Next time an e-mail will be sent out prior to making any such change.
