What field type should I use if I want the user to be able to enter a url and instruction text? Example: a url for the visitor to send a secure message to the user with instructions on how to use the url/message function. Such as a link to Google Hangouts Chat with text that states "You can send me a secure message with a Google account using Google Hangouts by entering my email address as a contact. Please do not send me emails do to the lack of security with email."
If I choose Link type, there is no way for the user to add a custom message to go along with it.
