ZTA at Univ. of Rhode Island?

[aephi alum]

I'm hoping you ladies can clear something up for me -

On the University of Rhode Island web site, I see a sorority that's listed in some places as Zeta Tau Alpha and in others as Zeta Epsilon Tau Alpha. The group is listed as an associate member of the local Panhellenic Association, and it's listed as having been founded in 2002. There's a photo on the URI web site that clearly shows young women wearing letters that say "ZETA", not "ZTA". I checked the "All the ZTA chapters ever" thread here, and it's listed as a colony for spring 2009.

What's the story? Was this a local sorority started with the intention of affiliating with ZTA, and they are now achieving that goal?

Thanks in advance.
