When I look at template tags, they generally look like this:
<?php previous_comments_link( __( '← Older Comments', 'blog001' ) ); ?>
The blog001 is the themer defined term for that skin. What I was wondering is, does that have to be different for each theme or can I just make it generic like 'wptheme' and leave it at that for all the themes I create. I also noticed it is used in the functions.php which is why I started to wonder.
