I just uploaded a few gadgets to Windows Live Gallery and thought I should share something cool I learned from Jay Fluegel, the PM for gadgets in Windows Live Spaces. If you see a cool gadget on someone's space that you'd like to add to your space or portal page, all you need to do is click the '+' in the top-right corner of the gadget as shown in the screenshot below and viola

That's pretty hot and brain-dead simple too. Definitely beats having to trawl Windows Live Gallery everytime you see a cool gadget that you'd like to add to your space or personalized home page.
