| The MailMan archives list page looks great. As long as it handles email replies, that's everything I'd want in for discussions. It even has regEx searching, which is something I'd actually enjoy using.

It has some real cool nerd features. Also very light on the server.

| I know that some folks never bother with the web interface, but if you ever want to look up something from the past, search through the archives, or look at a collection of files (say, construction photos), it's important to have a web portal into the list.

I spend time there reading the stuff you already know.

| Unfortunately, I don't see any reference to the ability to host group files/media in folders to which users can upload. It's not there in the feature list or the detailed news file.

Currently it stores files in the db, which is fine. I can then either put all needed pictures in a thread, or put in a directory very easily using common tools. It has a coming ability to store in a folder.

| If the ability to host a files section is included, or can be added-on (plugin?), then I'd say mailman is the way to go.

Me too. I mean there are probably plenty of other solutions, but this seems good. I am willing to try and break it.

| If mailman can't be modified to handle a shared files section, I'd say that a solution that has that feature is the preferable one.

I still got my mind open.
