Okay, so this isn't a priority anywhere and it's a single typo, but in the interests of looking professional, you might want to update _UE_LOST_USERNAME_PASSWORD_DESC in 'default_language.php' (components\com_comprofiler\plugin\language\default_language). Here's what I chose:
DEFINE('_UE_LOST_USERNAME_PASSWORD_DESC','If you <strong>forgot both your username and your password</strong>, please recover the username first, then the password. To recover your username,please enter your E-mail Address, leaving Username field empty, then click the Send Username button, and your username will be sent to your email address. From there you can use this same form to recover your password.');
Please note that I changed 'LOST' to 'FORGOT', but that is a symptom of the users on my site!
The actual typo was 'receover'. Like I say, nothing major...
Love this new version and its additional functionality.
and while you are in that file you could always update the following:
DEFINE('_UE_LOST_USERNAME_PASSWORD','Forgotten login details?');
which seems to reflect the excellent function, and helps with the questions that I am frequently being asked - 'I can't remember my username or my password' or 'I think I registered, but it doesn't let me log in...'
Thanks guys.
