It is very effective to separate topics with a horizontal line.
Humans tend to perceive that material that is separated from other material as different.
So, it is possible to discuss different topics on one page and separate them with a horizontal line. To insert a line, place the cursor where the line is desired and click the H. Line icon. You have some control over the appearance of the horizontal line. Move your mouse pointer over the line until the pointer turns into a double headed arrow. Then, click the right mouse button to bring up a menu box.
