Our Website Design is Terrible

Instead, I would like to engage the community: what are your suggestions for the design of our website? This could be in the form of a page mockup, a CSS stylesheet that would work with it, or even just constructive text suggestions.

I suppose I'll get nowhere with this, but I like old-school. I actually prefer the threaded nature of the old Usenet based on NNTP protocol, but if it's gonna be web forums, this is the style I like.

Another site I frequent -- SitePoint -- revamped the look of its forums from traditional (like this) to modern (like this: community.sitepoint.com/) and while they may look cooler, I don't think they improve usability or the user experience.
