Why thank you!
It took me a bit to figure it out but it's really efficient. It time-stamps requests and puts them into a spreadsheet. There, I can colour co-ordinate requests, which means I can keep on top of things easier. Me and my friend share our stock (He sends stuff to me) and we split everything 50:50. It's quite good, although, I'm working on expanding my cargo. Anything you want? Click the link to the request sheet and then click the link to my stock list. Fill out a form and then I'll contact you. SIMPLEZ!
If you want to use the idea, It'd be great if you could give credit, although, you don't have to.
