I've been a member of this List for a couple of years now, and I increasingly suspect that not everyone on the List receives the email updates at the same time. Two reasons lead me to this belief:
First, even though an update has just come into my mailbox (based on time-stamp and "you have mail"),someone that is selling something that I immediately contact invariably replies that the item is already sold. Of course I attributed this to the demand for the item, maybe I'm not as fast as I used to be, or the seller changed their mind...fair enough.
Recently however, I posted some items for sale. I was eager to see the posting so I kept checking my email. However, before the email containing my posting was in my inbox, I already had three listers email me that they wanted the item! Since FS items are often sold on a first-come, first-served basis, this system is only fair if everyone on the list is made aware of the posting at the same time, which is not to say that it isn't, but I wanted to bring my suspicions to the List's attention to see if others have had similar experiences.
