You have to add the HTML for your category-bottom at the top of your forumhome_level1 templates. So it will work like this:

header
--
category_bottom

category_top
category_middle (forums)
--
category_bottom

category_top
category_middle
--

Where '--' separates each iteration.

Of course the problem here is that you will have a category_bottom at the top of index.php without a table above it, and you'll be missing a category_bottom for the last category table. To fix this, go into your forumhome template and add the top and middle of a new table before $forumbits (add something like a user info box so it's not an empty table), and after $forumbits add the HTML for another category_bottom.

It's a very hard thing to explain, so I hope you understand.
