In addition to sitting with you, my brothers and sisters here at Treeleaf, I have been sitting with a small local group for the past three years or so (they even joined me for Jukai this year). Until now we have been meeting in the homes of members, and have not done much outreach into the community (word of mouth only). However, recently there has been some talk about possibly changing this -- working with a local non-profit multi-denominational "spiritual center" and/or making our meetings and sitting public (in the sense that we may list them in the local paper and such, not in the sense that we will be sitting in public).
Our little group is primarily Soto and Tibetan folks, and although some of the folks have been practising for decades, none of us is in a position to "teach". Which is to say, mostly we would "just sit", no teaching, and certainly none of us would claim to represent a specific school of Buddhism (honestly, being in a rural and conservative community, even using the "B" word might be a bad idea).
So anyhow, I am writing, because I'm curious if anyone has any experience in starting a local group, and if so opinions, advice, tips, or experiences to share.
