I have but one coment about some of the forum members on this site it is very unfair to pee on the forum sponsers if such behavior goes on it is a wounder that there are any sponsers left,I know if I was contributing to this site I sure as hell would not be for very long if such behaviour continues.I noticed it states that not to put negative feed back on the sponsers area -so negative feed back some where else is ok?
There seems to be some sort of trend going on with forum sponsers drobing there sponsership around north america-I wounder why?
