I'm not exactly computer website tech savvy myself, but if you do as I already simply and clearly explained, not in someones post, but in the subcategory or category or what-have-you, scroll to the very bottom of the screen, use the bar on the right side to make it faster if there are a lot of posts, you will find the text:

For example -- click on "categories" at the top of the page, or the "I<3GM SUPPORT FORUM" at the top of the page, or however you get to the begging support forum page, then click on "Beginner", then click on "Lights & Ventilation", then scroll to the bottom of the page and click on the highlighted "Why not create a topic?" part of the "There are no more Lights & Ventilation topics. Why not create a topic?" text contained at the very bottom of the page.
