Star Trek Eras: The Audio Series
The episode in question (about an Efrosian character by the name of Ra-tevnarem, a communications officer on the USS Potemkin) is going to be for their second season. Currently they are working on editing the third episode in their first season, so it's going to be a while before this episode is actually recorded and made available.
"It wasn't until after we had created the character that we realized that there was a bit of confusion about the race," says Jim - coincidentally yet another fellow Star Trekking librarian. "Using your article as a base, I've come up with some strong ideas that should go a long way toward... a comprehensive answer. I just wanted to say thanks and let you know that your work is proving to be quite valuable."
In the meantime, there are other episodes already available for download. The "new era" of Star Trek fanzines is online.
