Would it be possible to devise such a thing?

No, I don't have a perfect record, either, but I almost always acknowledge receipt. If I can't address it at the moment, I estimate a "get-to-it" date. At barest minimum, I acknowledge that I got it.

I for one enjoy the conversation around trades - both mine and others'. Not everyone is "chatty" but it seems to me a lot of the value of PB is in the interraction with other owners - as a voluntary community of baseball afficionados we can enhance the experience of all owners by contributing.

No, this doesn't mean I'm asking everyone to post on this board or send elaborate emails in response to every trade offer. But I'd sure appreciate it if everyone just responded to offers in a reasonably timely fashion. End of gripe.
