We had a number of successful meetings after the OMG Technical Meeting in December, culminating in a Kick-Off Meeting on Jan 6, 2014. At that meeting, we reviewed the current status of the project, and received great guidance and support from Kshemendra Paul, Donna Roy, and Richard Soley.
Going forward, we have decided to use GitHub as a repository for collaboration. For Phase 1 the repo is at https://github.com/omg-threat-modeling/phase1 and will host all relevant documentation and code. Starting next Monday, Jan 13, we will have recurring conferences from 2-3pm ET.
