is it somehow possible to send massmails als administrator to all users of a selected group?
or is there a way to get all emails in a list from a selected group?
i use Mysql with CrushFTP
Since you have them in SQL, you could certainly select the data in your own query to get the users...
Otherwise only the reports tab could get you this listing, or if you have the enterprise version you can use a scheduled job to get a list of properties from all users.
