(Except Forum Home, figures)
Yes because topics are supposed to be relevant/posted INSIDE a forum category.
So from the index of the forums, you can click directly on "Open topic" (for example) to access the "Open topic" forum. (that will prevent you all the trouble from sliding down and "jumping" to another part of a forum)
Also once from inside a forum or even a topic, you can click on the navigation on top of the screen ("Board index < General < Open Topic").
Each name is clickable, will take you to said part of the forum and prevent you from having to slide down to the bottom of the screen.
That's pretty much how forums software work in general.
Also I wouldn't advise making too much posts/topics in the "Open topic", but rather try to post where it is relevant. "Website issue" when it is an issue with the website/forums of Scirra.com, "How do I" when you have an issue/question about Construct2, etc...
The organisation is about to change anyway and forum names/organisation should make more sense to newcomers.
