missing some characters in line 13 of content.php

current:

<div class="entry-data"><?php pepmagazine_posted_on(); ?> __('by', 'pepmagazine') <?php the_author(); ?></div>

should be

<div class="entry-data"><?php pepmagazine_posted_on(); ?> <?php _e('by', 'pepmagazine');?> <?php the_author(); ?></div>

Love the theme, though. Easy to customize (so far)
