You need to create your own HTML mail, probably. You can do that with the MIME classes added in ND6, or with a third party product like our
Midas Rich Text LSX if that is too much work. Either would allow you to make the hidden part of the link. On our
website, there should be a link to the presentation I gave in Düsseldorf in February on the new ND 6 classes. Part of that presentation is some sample code for creating MIME e-mails, but it is a fairly simple example. Rocky Oliver might also have an article on MIME e-mails on his
LotusGeek site. (He certainly has other good stuff on there about new ND6 features that is worth reading)
