That is too bad indeed. We should find another opportunity in the

Would you be interested to summarize and discuss these results within an
Einstein Toolkit call? We usually use plain phone for the calls, but
would use evo as second option for opportunities like this, and we would
announce it accordingly.
The call is always open to the public anyway - please feel free to call
in. The next call will be Mon Nov 7th, at 10am central time, and usually
an announcement is sent the day before.
