I can get more through, and with pictures, to my Yahoo groups than my MSN groups with others' very interesting posts as well. If you follow the links at the bottom of the front page, you will go through ALL my Yahoo groups, although two or three do not have open messages and joining is required. This first group is the best for over-all posts.
All these groups also have excellent file pages.
is an example of a closed group where membership is required.
