In a 12&12 step meeting I used to go to regularly it was written
right into the guidelines before each meeting. It basically said "No
cross talking about the personal problems of the other persons who
have spoken before you. If you wish to discuss their personal
problem with them please do so after the meeting." You could give
them advice such as get a sponsor, try different meetings, or talk
about your similar experiences, but keep it on yourself when your
speaking at the meeting not on them.
