I have an article published in the January 2012 issue of Friends Journal! It's about some of the reasons people do "unacceptable" things in Meeting for Worship, and how those reasons relate to accessibility and ministry.
The piece appears on page 13 of the print edition (how appropriate!) and is titled, "Accessibility, Handwork, and Ministry in Meeting for Worship."
(The January issue is not yet up on the Friends Journal website.)
