We have had discussions in the past about forums, facebook, email groups and so on but I hope that Friends and visitors to this site will choose to comment here (on any post or page inviting comments or replies) and establish a conversation in this way.
However, we don’t often draw attention to what is happening with non-theist Friends in the USA and internationally.
There are numerous links to the US NTF site at various points on this website (see, for example, the bottom of the right hand column or scroll right down on the mobile version). The US email discussion group is still active and can be accessed at the top of any of the US pages or directly here: https://groups.google.com/forum/?hl=en#!forum/nontheist-friends
A recent discussion there on meditation, god and non-theism includes an interesting youtube video. This can be accessed via the email discussion group here: https://groups.google.com/forum/?hl=en#!topic/nontheist-friends/myIj6VLE8hs or directly from youtube here: https://www.youtube.com/watch?v=TBGIqp8EKfg&feature=youtu.be (conversation starts 17 minutes into the video and is certainly worth watching for 20 minutes, even if the full 1 hour plus is too long. After that 20 minutes there is a lot of discussion about Barclay, Quaker belief, Richard Dawkins and so on).
