I have just added a new Mailman integration product to the Zope site. It is slightly different architecturally from other Mailman integration products in that only a single instance is needed in order to manage all lists. The product is in its infancy, but is being used in production at my company. In the near future I will be adding full list configurability (all the options: General, Privacy, etc) to the product. You can find this product and some external scripts for integrating with mailman at: http://www.zope.org/Members/khcarlso I hope that some find this useful! Kevin
