What does the check box found in some posts do?
Some posts in the various groups have a check box next to the bookmark button in the upper right of the original post. I've check it on and off here and there but can't tell what it is for or what it is supposed to do. What is it?
Also, since this is not an Idea, but rather a question, it does not really seem to fit in this category. Why is there not a category for Communities under Q and A?
