Facebook user named fb456345

Mike,
Sean's right. If you have the Registration Flow set to "Automatic", JFBConnect generates the user's name automatically based on information from their Facebook profile. You can change how the name is created with the "Auto Username Prefix (Automatic Registration):" setting. On this site, it's "firlas", so your username was created as 'miklaw', based on the first 3 chars of your first and last name.

Hope that explains,
Alex

Awesome! Glad we could help!

On a side note, if you haven't already, please consider leaving a rating and review on the Joomla Extension Directory for JFBConnect, or our support. It's certainly not required, but very appreciated!
