Is there anyway to remove the autofill username of the facebook connect plugin? Some people don't want their facebook name associated and register without realizing this should be different than member name.
Open /myfbconnect.php, find:
$username = "<input type=\"text\" class=\"textbox\" name=\"username\" value=\"{$user['name']}\" />";
Replace with:
$username = "<input type=\"text\" class=\"textbox\" name=\"username\" value=\"" . htmlspecialchars_uni($mybb->input['username']) . "\" />";
