At the forum homepage, just like how you were able to locate your cheat, thats how you should locate categories in the forum.
the categories are not the one scrolling on your left, those are new topics and comment posted by members.
there are so many categories having titles like Mtn Fbt/Cheats For Free Browsing, religion , news, politics, buy & sell, iOS / Apple Phones and Tablet, and lots more, there is a description under each category telling you what the category is about...
just make sure your topic is related to the category you will open,
When you open a category, you will see new topic just like you described above, example if you open politics. make sure your topic is about politics only and nothing else.
Notice some of the topic have been locked....
