Yes, an important point. Both the mailinglist and individual threads should be easily bookmarkable. I assumed the inclusion of that requirement when I said they should be indexable, but it's worth clarifying

While the actual software used doesn't really matter, I strongly recommend using a well known platform such as mailman. My hope is that the list archives can be decentralized into systems such as Nabble. glassfish-dev is an example: http://www.nabble.com/java.net---glassfish-dev-f13451.html
