Migrating a website from Mambo to Joomla. I would like to have a guestbook on the Joomla website with guest having to identify country of residence and the country's flag shown when the guest's note is published. Current Mambo site has this feature but unable to get a Joomla extension with similar feature. Additionally I would like the current entries in the Mambo guestbook to be transferred to the Joomla site's guest book.
