thanks for the replies, and Kitty Hawk, that Search suggestion is a good one, which I'll employ.
Twistandshout, just highlight the portion that you want to quote, right click, and copy. Then, put the curser in the box where you post, and hit the button that is second from the right just above the box. It has a picture of a cartoon quote in it. Then put your cursor between the ] and the [/ , right click, and paste.
It's really easy... I hope you can follow my explanation.
