Rich, I'm being an ass and picking apart your statements... the same thing you do. Enjoy the sparing.
In all seriousness, this is a close community and that's why we all belong to it. Most people here know your tastes and if they ever came across the poster you were looking for, they would tell you. If the quad was ever listed for auction, you'd probably get 5 PMs about it before Mel outted the auction to rest of the anonymous APF guests out there who also collect Chandler. As we all know, it only takes 2 people to run up a poster price.
Guests typically outnumber members 5:1. There are clearly lots of collectors on this forum who don't contribute to it. For those who think that outting this information doesn't have fiscal consequences for your friends here, you are deluding yourselves. And as others have pointed out, it isn't about being cheap or being whiny. It is about being courteous and respectful of other members.
I believe in looking out for fellow members. That includes alerting them to posters that fall in their range of interests, AND not screaming it from the rooftops to their bidding competitors. Hell, I bought you a Chandler poster you didn't have simply because I thought you would appreciate it. It wasn't expensive, but it wasn't free and it did take effort that I didn't
have to give. I have done it for others as well. But again, this is why we have a close community and a PM system.
