First off, very glad to hear you're enjoying JFBConnect. It's taken a lot of work, and feedback from users, to make it what it is!
As for email as username, we're planning to add this as an option, hopefully in the next release. Anyways, just to make sure, you're using the Automatic Registration flow? If so, here's the quick code change that should work for you, if you're up for a minor mod.
In the /components/com_jfbconnect/models/loginregister.php file, around line 68, you'll see the getAutoUsername(...) function. Simply add this line after the {:
So, it should look like:
function getAutoUsername($fbUser, $fbUserId, $usernamePrefixFormat)
{
return $fbUser['email'];
if ($usernamePrefixFormat == '0') //fb_
{That will simply skip your selected auto-username setting in JFBConnect. This is completely untested, so please make sure it works, but a pretty simple change
Let me know how it goes, and good luck!
Alex
