Convert "LimeTouch" at the top to an image and add a shadow effect, bevel and slight contour. Make it pop out. Add "text-decoration: underline" to all anchor links both normal and hover so they stand out without any color addition. Add a "Find" button on the right of the search box - do not rely on JavaScript for the form submit. Allow larger avatars, i.e. at least 75x75 but 150x150 would really make each submssion entry pop and be distinguishable from others. And your layout is perfect for converting to a liquid layout with minimal pain - maybe make 85% of the page the content area and use a 15% darker margin color (border) set with either a simple gradient in the black/gray family or a dark solid gray you use now or contrast solid color you can come up with - so as to frame your content area (at least left/right if not top/bottom). Cool, eh?
If you don't like any of these suggestions you might, at this point, please add a hint or two as to what you might like - be general, we'll get specific, so we can post suggestions that don't make it boring for those following this thread if we keep throwing out blind suggestions and you keep simply saying yea or nay, heh! This isn't an angry reply, honest. Just being truthful, but helpful at the same time, and always keeping in mind your original design. Thanks!
