Does the forms 'Modify Details' and 'Send to Friends' work on the web or only in an email?
The 'Modify Details' and 'Send to Friend' forms can only be linked to from within an email campaign as they are email/user specific and need information contained in the email to allow you to perform the requested actions.

The 'Modify Details' form needs to be authenticated to make sure the owner of the email address is the only one who can modify his or her details so they will only be able to visit the Modify Details form by following a link that was included in an email sent directly to them.

The 'Send to a friend' form needs to be included in the email campaign as the form needs to know what email to forward and who it is being forwarded from.
