It took some e-mails to the author of BroadBand and an hour of head scratching and trying things until I found that I had the wrong SMTP address specified. The e-mail now works with BroadBand. I spend some time customizing the various options, and testing it out setting up some forums, adding messages, adding users, and trying things. I really like it. There will be a bit of tweaking to make it look just right, but for now it is just about there.
