I agree. I think that in many ways, one should consider that the OP has the 'intellectual ownership' of the discovery of a mistake/trick fare and it is up to him/her to cross post if he/she wants to. If anyone else wants to cross-post, I think they should ask him/her permission first. In other words, I'd always assume that someone willing to share a great discovery with me as a fellow FTers is sharing it with me as part of a given community of people who share a passion for travelling, flying, and discovering great deals, and not as a member of humanity (or its internet connected sub-part) at large
