Yes...that's the C-M group I referred to in my original post. I've learned a tremendous amount from folks in that group, as I have here. In both groups I've had a few laughs as well.
After reviewing the responses here, and in the C-M group, I have what I think is good idea of group behavior norms. If I recommend that a list of common courtesies or rules be adopted, I'll use much of what I've read to compile such a list. However, after some thought, I don't think that will be necessary. For now, I may just occasionally make a comment about things that may be irritating to others.
Example: At one time I suspected that someone may have "shared" the group's contact list for marketing purposes because I suddenly received snail mail that didn't fit with my profile of activities. I could have been way off on this, but I did mention it during my regular announcements...just in case.
I'm extremely thankful to the Universe and my creator that I never experienced what some of you have. Pardon my brag, but my group is quite considerate and I've decided that an official list of rules and courtesies may not be necessary.
Thank you again tubenet buddies.
