I feel like I'm starting to need a small mailing list or two for Business Reasons and while I'm looking at various options, is there any off-the-shelf thing that'd allow me to set up something that I can allow other people to use as well? Do people want more options for this? It's very much the kinf of thing Chinwag could be doing.

Ghost does this, right? It seems a bit more heavyweight than I think is really necessary but if it wasn't just for me maybe it's viable?

Anyone have any recommendations or alternatives that do a good job of making management and post authoring easy for people?
