Changing "Members" to "Subscribers" with eNewsletter

What file do I need to go into, control find all mentions of "member" and change all to "subscriber" in order to effectively re-word this aspect of eNewsletters?


I'm guessing this won't work ... so, can anyone please point me in the right direction.

I feel the wording of this particular plugin is important, as I'm not running buddypress so "members" will feel alien to my users. Thanks!
