Hi Karencon. Welcome to the board.

There are two different ways of looking at threads on this board, flat mode and threaded mode. In flat mode the posts are all visible at once strung out vertically on the page in chronological order. Many of the of the people on this board choose to view the posts in flat mode for a variety of good reasons that we need not go into at this time, but one of the consequences of viewing in this mode is that it is not always immediately obvious what someone is responding to. There are several methods of addressing this issue; one of the more popular is to quote a piece of the post to which one is responding. This is particularly important if the post one is responding to is not immediately above the responding post. This can be a little hard to tell if one is in threaded mode so it is probably best to quote. Just saying, e.g., "I agree completely" doesn't work.
