Advice on leading sitting group I've been practicing for about a half dozen years now, have been fortunate to go on several retreats and have a consistent practice. Where I'm currently living I really don't have access to a sitting group I don't have any delusions about being a teacher but several people who know I sit have expressed  interest in learning.

I was considering doing simple guided sits. Are there any cautions? Should I probably not pursue this without training?
It is good to start a sitting group. My suggestions are: 


Make the group as informal &amp; self-reliant as possible. 'Self-reliant' means making it clear that meditation is an activity of self-practise &amp; self-endeavour; that the group provides individual members the support &amp; opportunity to develop their own practise. 
Make it clear/overt it is simply an informal sitting group rather than a    formal teaching facility.
Provide guided meditation only to newcomers or when introducing a new
practise.
Keep guided meditation short (e.g. 10 - 15 minutes) &amp; main meditation long
(e.g. 30 minutes).
If there is no guided meditation, do a text reading at the start, 
contributed &amp; read by yourself or by a member of the group.
If possible, end with tea &amp; formal group discussion on a topic,  chosen
by yourself or by another member of the group.
Be as 'democratic' as possible but without expanding into other
spiritual traditions that may cause confusion.
