Ask Agaric: Getting the E-mail Addresses of Your Site's Users
How do you harvest e-mail lists for all of the site users?
(Agaric note: Harvest is often used in the context of spammers "harvesting" electronic mail addresses; this is a matter of the site owner getting e-mails provided by site users, to which the site owner already has access, in a useful form. We skipped the terminology sermon and just wrote back...)
There are a couple enhancements that could be made to the site.
One is a module that allows configurable views to be downloaded as comma separated value (CSV) spreadsheet files.
Another is a mass contact module that would allow you to contact users directly through the site.
