I started using UPS as one of main cuz my friend started working there. But since then I cant say I had any serious problems with them, everything comes on time and safe, the impression is yet positive.
Create a category and start pinning everything interesting that falls into it for you. Its just that simple. Save just a beatiful photo, or a great design you might use later when you got some spare money. The only thing you need an invite to join =/
