Importing a contact from an eventIt is possible to create a contact from an event if the event has a certain format. This can be useful to provide a contact to several persons e.g. by using a shared calendar where the event is entered by one person and used by one or more other persons.
To use this function you have to turn "Settings", "Display and Use", "All", "Detail view", "Import contact button" on and enter a regular expression under "Import contact prefix". The prefix describes how the title of an event that contains a contact should look like. E.g. if such events always start with "Contact: " you should enter "^Contact: " under "Import contact prefix". Then the "Import" button will appear for all events that have a title which starts with "Contact: ".
