It's a shame that hot wfp users don't post much about the system, but they do have a point. It must be disheartening to take the time to write about a personal experience of it only for people who have never used it to say what's the point and is not neccesary, why bother?
Everyone has an opinion but where experience of using this system should count as the only one, most people would get sidetracked by the naysayers, without knowing who has knowledge and who doesn't.
Fortunately it will change because a couple of years ago it was similar about trad and wfp, then the diy wfp cowboys.
It's very hard sometimes to distinguish the wheat from the chaff on certain topics.
