I just want to point out that this is an invaluable service being offered here. In our practice it is not necessary, but fulfilling and useful, in a sense, to communicate with other practitioners. For those who would otherwise not have the chance, this is a great place for it.
A Sangha gives us a chance to share our practice with others. Even if we only say "Hi. How you doing?" or read what some one said. It puts us on the right path.
A Sangha is a group of people who come together to study and practice the Buddha way. What does that mean? And where does that line get drawn?
Now, it was mentioned before that this place is "mind to mind", and in this way is not the same as a regular Sangha. Not so. What's central is practice. Of course, sometimes, we have to come back to mind in order to communicate. Dogen showed us that with the Shobogenzo.
Whether through choice or having no choice, this is Treeleaf Zendo. Doesn't mean anything special or astounding. We don't have to make it a big deal; it is what it is.
With that said. We don't have to hang around here all the time. We can take breaks and maybe drop it all together. There is no you or me. There is only...what? Exactly.
As Shunryu once said:
But until then...We should be ready to give up the Zendo.
And Keishin's word's fit here:
No separation.The Sangha is everywhere
