Yes, I do read these comments and all posts that are made in TechNet.
I don't think it will be smart to rely on a default setting that you can set, since that would mean that you would click the button without thinking twice, and that could proof disastrous as you pointed out yourself.
Most people do indeed have a local copy of their stock in a stock program, or in the least in Excel. Only some customers with few listings don't have this. It would be wise to keep a copy of your listings, at least in Excel. Can you tell me what fields are missing in RapNet XL's 'my stock on RapNet'. All fields should be there, but if something is missing, we can fix that. Make sure to get the latest version of RapNet XL. Any uploaded certifcate scans or diamond images will also stay on our server, so even if you reupload, you can always reconnect the images and scans back to your diamonds.
Just that you know, that in most cases of people loosing their stock listings, a few days later, our customer service can still retrieve the listings, even if it no longer appears under your stock in RapNet.
