Alice another great guide as usual.
Something that's not quite clear, and may be good to add.
In section 16.3.2.3 Selling at auction... you say:
'Regardless if the item sells or not, you will get a message what happened. If your item wasn’t sold you have to go to an auctioneer to get it back again'
Nobody ever says whether you get your auction fee back if your item doesn't sell. I think you don't, but maybe an expert auction user can correct me. It would be good to clarify this in the guide.
eg. 'Regardless if the item sells or not, you will get a message what happened. Also if the item does not sell, you will
not get back the auction fee you paid when you placed the item in the auction.'
