It's been awhile since I've scrapped & I can't remember - What is considered a "GDS product"? I have TONS of stuff that I bought a couple years ago & was wondering if it's still considered GDS even though the designers have retired or left this site? Also, what if the designer is still here but the kit itself is retired? Is that still considered a GDS product?

I'm trying to do the challenges & for some of them I need a certain amount of GDS product so I'm trying to determine which kits I can still use. Any help is appreciated!
