Hello @Jeremy,
I agree with Johnny that if we are looking for a high quality performance then perhaps tomorrow (July 23rd) can be used as a dress rehearsal or intermezzo for a later date (any Tuesday is open except for August 13th’s Café on Quantum Entanglement, Quantum Coherence and Quantum Consciousness). If you would like to join us tomorrow, we can ruminate about the contents of a future Café. If nothing else, it would be a pleasure to speak face-to-face and share a conversation 
And side note: if the Tuesday time is a challenge for your current schedule, we can seek alternate hours.
