From the guidelines: Does mean no users at all? Not even the administrator? Let's say my username in the imported data is the same as what I have in the destination forum. What happens? I'm thinking that a super admin with a unique username should exist so that this super admin will not acquire anything during the import. The super admin is then possibly accessible if anything goes wrong. I see that a super admin can only be created using myforum/library/config.php It currently contains $config['superAdmins'] = '1'; Does the comma separated list go on a new line directly after this? What is the correct syntax?
