Help the Professional chapter improve how we manage mailing lists!

We currently have mailing lists set up on our webhost (based in EZMLM, http://www.ezmlm.org/ [1]). This is an adequate solution, but can be a bit awkward when it comes to maintaining the mailing lists.

Help us investigate alternate mailing list systems, such as Dada Mail (http://dadamailproject.com/ [2]). We'd like a solution where is is easy to add/update lists and members of lists.

Thanks!
