Amazee has provided a workspace on their system for this.
A new repo has been created and affiliated with that workspace. The repo is at https://github.com/drupalcontributiongroup/drupalcontribution-org
MegaKeegMan, myself, and gusaus are added on the Amazee side.
At present, additional work needs to be done to get the repo Lagoon + OpenSocial (+ DrupalContribution.org) ready.
One we've got something deploying properly to Lagoon, we can look at DB migration, etc.
