The system as I have envisioned it will work like this:
1. You go to a page on the SB.com website and login like you would any website. I would create credentials for this login, and the administrators could provide credentials to anyone who wants to help with parts management. For now, I imagine that these people would be Gollevainen, TimothyC, Acelanceloet, Hood, and a few others who manage the parts sheets.
2. You would then click on an "add part" link and be taken to a form. In this form you name it, fill in any other information, and submit the file for upload. I would place in a hard requirement for .PNG images under 50kb or so to make sure that no JPG nonsense gets added.
3. Once a part has been added, parts administrators could then click on any added part and have the "edit" option visible. This would allow them to update the name and other information as well as upload a new part to replace an older one. I might be able to create an option to keep old versions on hand but I don't see the need for that.
4. Parts administrators will also have the option to delete parts from the database.
This will not require any extra work for Gollevainen unless he wants to start cataloging the parts on the site himself; I imagine that this can be more than taken care of by our eager parts sheets contributors.
