In the beginning, many of the members of AA gathered at people's home nightly, some were there as Bill W. and Bob opened their homes to housing those who were detoxing or in early recovery. Basically, they "fellowshipped" nightly and had one meeting a week.....
We don't have a need to do this today, although I know of people who continue this open door policy and of others who always have sober company in their homes on a frequent basis.
I once heard Bill W. on a speaker tape at a convention. He was speaking of the future of AA and mentioned that "AA can and must change." I believe he was a forward thinker and knew that AA must change with the times, as it has.
Works for me!
