Broken translation string

In line 763 of class-forms.php there is an error which breaks an translation string:

$activate_message = __('<p><b>' . __('Please activate your account :', 'userswp') . '</b></p>
            <p>' . $message . '</p>');

Even if this would work there would be missing the text domain for the outer translation function. But I think it would be better to remove the outer function completely:

$activate_message = '<p><b>' . __('Please activate your account :', 'userswp') . '</b></p>
            <p>' . $message . '</p>';

Thanks for considering.

All the best,
