Thanks everyone who replied and e-mailed me on this. I appreciate the thoughtfulness and civility of the responses. I don't have any definitive answers or "rules" that apply to the issues I raised but I think they are worth thinking about. I just hope this was a win/win for all participants AND ConAgra so that they'll try again. I did love this promotion (picked up 10,500 miles) and did become a convert to their low-fat ice cream. And I'm glad I wasn't trashed like some artless spammer. Thanks again.
