Newbe getting lost on email-invitations - by: arthur

Hi everybody,

I just successfully installed limesurvey on my webserver.
Creating a new survey prooved to be very intuitively.
Getting invitations out into the world was not ......

Central or decentral participant databases, "attributes" to be linked to participants, codes to be provided and connected to participant(groups)?????????

Can someone pls describe a simple step-by-step instruction on sending mail-invitations.
Thnx for your help,
Arthur
