I actually had seen the article cited, "How to make an unsubscribe footer link for mailing lists in Mailman," because I searched the forums for an answer to my question before posting. Unfortunately, that post did not answer my question.
I apologize, I may not have articulated the question very well.
To the best of my understanding, after consulting the Mailman 2.1 documentation, which I also did before posting my question to the forum, setting the OWNERS_CAN_ENABLE_PERSONALIZATION = 1 in mm_cfg.py will enable personalization for *all* owners.
What I am trying to find out is if there is a way to enable personalization for only particular, specific, individual owner accounts, not *all* the owners on the shared system. I hope that I am making the distinction well enough.
