I am sure the answer to this is somewhere out there but I can't seem to find it. :)
I am setting up a couple of distribution list for a department of ours but would really like them to be able to add and remove members. I was thinking that with version 6 we were supposed to be able to do that. I can't find a process that allows me to set a user or two up to do that.
if I understand your question:
But in zimbra admin console, you can create a new distribution list and you can add or remove members in it
I guees you asking for role based admin delegation. Ofcourse you can create DL admins to do only DL related jobs, also you can create your own groups based on different roles.
Better do read the Administrative Manual of the release 6.0.
