I am excited to announce that the design search function now also searches through the design tags and info, as well as the name and description. this is another step towards a more advanced search option.
In the meantime, here's an example for what can be done with the search function. lets say you want to search for a design where the primary color is gray, is tagged with the tag 'blog' and is XHTML 1.0 strict. you can enter this in the search box:
gray blog strict
Give it a try! works with design name, description, license, validation, color and tags.

woohoo, way to go!
