I so often see where some entries refer to the "page number" on the topic. That doesn't work the same for everyone. It depends on your settings and how many posts you choose to have on a page. The choices range from 5 on a page to 40 (my choice) per page. Having more per page eliminates having to constantly be clicking on "next page".
For that reason it is important to refer to the "post number" of the topic.
To change your choice for number of post to each page, go to the top of the page and click on "Settings" > My Account >General Settings >scroll down the page to >Number of Posts to show per page - then click on the box showing the number you have presently and it will give you the choice of 5 - 10 - 20 -30 - 40. Wa-La. Your done!
I hope this was helpful to someone.
