For as long as I've been a part of the community (over 6 years now), it has always been my impression and belief that auction times belong to the auctioneers. As a friend pointed out - sims can't build stages, perv cats, advertise them or call a panel and sell a kitty - the auctioneer does all of that so the time slot belongs to the auctioneer (I'm talking about you, Kiki
). Sims host the auctions and provide a place for the auctioneer to provide their service. This arrangement is beneficial in a number of ways for both the sims and auctioneers. Typically, the auctioneer is given an incentive to host their auction on a sim such as free rent for a shop on the host sim. The sim benefits by the traffic that the auction draws and will consistently get that traffic. And the auctioneer benefits also by being exposed to other patrons of the sim. It's a win for all.
However, I've noticed not all subscribe to this belief so I thought I'd put it out to the community as a whole and see what the prevailing thought was.
