This looks exactly what we need.., we have multiple joomla sites and a vbulletin setup and badly want to combine all logins across the various sites..

The question that rises here though is how it treats existing users in both DB's ?, i.e. will it simply overwrite the users from one into another DB, what happens if someone has the same login on joomla as someone else in the forum ?

Starting blank with our user DB's isn't really an option..
