i used the S&W Forum system of contacting our legislators on gun control. Boy, did I get responses: The President, both senators, my Federal Representative, State Representative and State Governor. I got no responses when I used another syatem a month or so ago.
Of course, most of them were merely stating their position, with no attempt to counter the arguments we were submitting. However I believe that the number of people submitting messags will at least get counted and will prevent some of the more wild-eyed legislators from promoting extreme measures (Mr and Mrs North America: turn them all in).
One down side: now I'm on my federal reprsentative's e-mailing list and I'm getting all sorts of messages that I don't really want.
