Can I keep all information of all group members private?

Question

I'm debating adding another group to use for my employer, but would need to keep all information private, as per our privacy standards. It would be used for a lot of communication going out to members, and some (little or none) between users.

Answer 1

in order to keep the e-mail addresses private, you'd have to select the option to allow members to hide it, but while on the group their yahoo ID will still be visible if they posted. also, each member that joins has to select to hide their addresses.

this setting is located in management, under group settings membership
