I'm new to Amazon S3, and am having trouble finding information on exactly how to set up the buckets and access policies needed to use it with aMember. From what I've seen in the forum here, I need to set up a IAM policy, but I can't find any specifics on exactly how this is done. Can anyone point me to a detailed step-by-step guide on this? Also, do I need to set up separate buckets for each product, or will all products go into a single bucket? And one last thing -- I have all my product files currently on my VPS, and would love to transfer them directly to S3. Any hints on how to do this? Thanks.
