Why yes you can!
If you're trying to find someone (like me - Amanda) but don't want to go looking through the Members pages... then search me!
If you're trying to find a blog post about a sale, then search for it!
Maybe you just want to see all photos of bracelets.... search!
Where is this wonderful search tool you ask? Right up at the top right corner of your browser. See the white window beside your name, and the word Search? Type in whatever you're looking for here (the more general you are, the more results you are likely to get), and hopefully it will pop up in the search results!
