There are a lot of people who come to these forums for help but it seems to me that there is more arguing, bickering, and flaming than support.
It also seems like there are a lot of attacks on zappers by some who have never used one and some others who claim to have used some but do not seem to have a clear accounting of what zappers do. Some do not even seem to know the definition of a parasite.
It would be a lot more helpful if people would only talk about things that they are actually reasonably experienced with.
