Hi to all. I need to create a new field (second e-mail field) in the person card. I tried to solve this problem by Tools->Admin->Presentation->Forms, but there is possible just to add a field (and change its name) from a default list, so it is unreasonable. Thanks
You need to activate a custom field for this and then put it on the form. Go to Tools>System>Data>Custom fields>Person and select a short text (or longer - 255 - if 40 is not long enough for your emails). Give a name (eg second email) and click the Activate for all categories.
Then you will find it is available for adding to the form.
