Hi, I made long times ago something similar in PloneGazette : when subscribing, an anonymous user receives a mail with a cryptic URL. Clicking on that URL from the mail validates the subscription. As long as the subscription is not validated, its mail address is ignored.
Anyway, someone who has several mail addesses can vote in the poll as many times ;) HTH -- Gilles Lenfant Le 21 avr. 2010 à 23:55, Maurits van Rees a écrit : > Hi, > > I've got an idea for an addition to PloneFormGen (in a separate > package).
