Not interested in moving my spreadsheet to discogs. Right to privacy and all that.
If I ever sell any, it's mostly just bringing to my local record store, and sold one or two on eBay. I am registered on discogs just so I can get market value of records I look to buy.
BTW, 98% of my records are bought new, so I don't have a RCM. I don't agree with those who say you have to clean them right out of the factory. I brush them to remove dust before every playing. A long time ago I was told by a well known respected dealer in my formative years that if a record is clean, don't wet it. That's when I stopped using my Discwasher brush and fluid (remember those?) and went to the Audioquest and Hunt style brushes.
To test my theory, I took a few records to a dealer who had a RCM (I think it was a VPI) and brought a few of my oldest frequently played audiophile records and played them before and after cleaning and didn't notice a difference. Nor did the dealer trying to sell me the machine. He admitted it was mainly for all the people who buy used records below NM out there.
