It's a LOT to slog through - there's no simple "here's what we are, here's what we do" pitch. But wading through it all, it *seems* to be a tool that allows for multiple text messages to be sent to cell phones at once - and for text message-based groups or "cells" to be created where any member can text members of the group.
In a slide show presentation, there are these testimonials:
We used [Celly] to put out the SOS that Occupy Wall Street was being evicted from [Zuccotti Park]. That text message instantly notified over 5,000 people - and was directly to thank for turning out all those people who came to be witness to history that night.”
Shawn Carrie, member of Occupy Wall Street’s Tech Ops Working Group
“I love how @occupysandy ppl using Celly networks 2 share news in real time, better+faster than news orgs :)”

“Celly is changing the face of education! With Celly, cell phones have the potential to bridge the gap between the home, school, and social media world.”
Melissa Seideman, History Teacher, Haladane High School, Cold Springs, NY
“Every family, work grp or block of neighbors should have: http://cel.ly”

Anyone out there use this tool? Would it be something the person who started this thread could use?
