Four new ones. I'm especially happy to have SPSFAQ090112, a Categories Web Part that displays the categories in a Workspace in a sitemap-like tree. It's a clever piece of code since it only reads the WebDAV source once. We've got Sandor Palfy to thank for it!

SPSFAQ090112 - Does anyone have a Web Part that displays a hierarchical list of categories in current workspace?
SPSFAQ030143 - Is there any way to decide if a given document url resides in a smart or normal folder?
SPSFAQ030144 - Does anyone know how I can declare my own functions in a VbScript part?
SPSFAQ060151 - Is it possible to search by a specific Content Source?
