The theme -- which you can blame on me -- is also extraordinarily dated and is starting to break under modern browsers
An aesthetic aspect of the theme is the (IMHO) over-use of horizontal lines. Almost every single object and element of a page has a horizontal line under it, and then they are all separated by horizontal lines on top of that. Especially the "Site Navigation", "Recent Threads" and "Online User" blocks, where every single link is underlined, and completely unnecessarily so, since everyone knows and expect those entities to be clickable links anyways. At least move the lines to a mouse over state. Please!
