Hello Lucas, Johnny, Luciano, Leo, Swapnil,
The CarpetX developer mailing list is at:
http://lists.einsteintoolkit.org/mailman/listinfo/carpetx-developers
That I mentioned in today's CarpetX call would be nice if all CarpetX developers (and early users) could join (to simplify reaching out to all).
Gitter / Matrix should also work to reach out to all and only requires a GitHub account:
https://app.gitter.im/#/room/#EinsteinToolkit_CarpetX:gitter.im
Though you should wait until tomorrow to sign up since there will be (should be actually) downtime due to maintenance today and thus registrations today may get lost.
Yours, Roland
