Hi,
we’re running the FOSSASIA Summit Singapore from March 14-17 this year and we are using emberjs for our event system at https://eventyay.com.
We also participate in Google Summer of Code and would love to get more people on board and connect with you. You can talk to us on Gitter at gitter.im/fossasia/open-event-frontend and check out our issue tracker here: GitHub - fossasia/open-event-frontend: The frontend for the Open Event API Server https://test.eventyay.com
All the best and Happy Coding!
Mario
