I installed Docman and have been trying to get the group email notification option to work for a couple of hours. It's there in the configuration, but the tool tip makes no sense. After a little research I discovered that the tool tip refers to another setting that has been removed in this version. Maybe the developer just forgot to remove the radio button. It doesn't work, so thought I'd save others the time I wasted. There is a plugin that will notify the webmaster or uploads, but it's not at all the same thing as group notification. Otherwise looks like a good extension.
