Oh okay! I understand now but this person was only looking for 3 pokes, not being free to other trades so he got move to the quick trade thread. Anyway there has been a mass outbreak of wrong threads (breaking the rules) from the new members!
Well the rule is you must be offering and requesting at least 10 pokemon, but you don't have to be specific with what you're looking for. I mean, if you're really only looking for 1-3 pokemon but you still want to keep a trade thread, just say you're open to other trades or something and it should be fine.
