QContacts is a contact manager component derived from com_contact, the standard component distributed with Joomla!, and offering several additional features. 1) More contact fields: Yahoo Messenger Id and Skype Id to provide your visitors with an alternate way to send a message to the contact. 2) Up to 3 custom fields can be added to the contact form. You can choose each field's type (text, textarea) and whether the field is optional or required. 3) An anti-spam verification image (captcha) can be added to the form. Contacts data and categories inserted in com_contact can be imported into QContacts. Online documentation is available at the website.
