Thinking about your site's design, UI and flow

If nothing else, you may want to scan through this site and see if it gives you any ideas: UI Patterns and Techniques

From the site:

Each of these patterns (which are more general) and techniques (more specific) are intended to help you solve design problems. They're common problems, and there's no point in reinventing the wheel every time you need, say, a sortable table -- plenty of folks have already done it, and learned how to do it well. Some of that knowledge is written up here, in an easily-digestible format.

By the way, when I say "UI," I mean Web sites, desktop applications, and everything in between (Web forms, Flash, applets, etc.). I believe that over the next few years, Web applications will become more richly interactive than they are now, and the smartest Web designers will use the desktop world's hard-won knowledge of how to design good interactive software. Likewise, desktop applications will gradually look more like Web sites, with better graphic design and more Web-style navigation. I will make no assumptions about how or when they will converge -- they may not, ultimately -- but stylistically, there is some common ground already. Thus, you will see examples from both worlds in here.

This is another site offering ideas on Web design: Basic Web Design. From the site:

This course will introduce you to the fundamentals of website design. The course will begin with a course Overview. Next, in Section One we'll explore a practical design process that can be used to create efficient and effective websites. After that, in Section Two, we'll learn how to technically build a basic, two page, table-based site using Dreamweaver. In Section Three, we'll learn about growing and modifying a site over time to include more content, and more functionality. By the end of the course, you should be able to design and build a basic website.
