Create a mailto: hyperlink column using a Person column and another column in SharePoint

Question

In a SharePoint calendar list, I have a Title column (single line of text) and a Contact column (person or group).

What I would like to do is create a custom field for a RSVP link. The link would be a "mailto:" url using the Contact column's email address and the Title column's value for the subject. For example: mailto:[email protected]?subject=thetitle. The link would be shown in Display view of the event item.

Is this possible? How would I be able to go about doing this?

[Added Question]

Could this be done using a computed field or custom field? If so, how?

Answer 1

Have you look at calculated fields? I think that it should be doable using the CONCATENATE function.
