Am I missing something on VoiceThread?

I use VoiceThread as one tool for a digital storytelling class I teach to teachers. I logged in today to refresh my memory of how things worked. What happened to the free educators accounts? Now they have the ed.voicethread.com that costs money. If I understand correctly, we are otherwise restricted to 3 voicethreads per customer for free. Am I missing something? This is becoming less of a "cool tool" and I'm disappointed.

Any insight is appreciated
Thanks!
