[Re: vc wave select]3900 found too

[smerf]

Welcome to the Club!! I try not to think anymore. I have had inventions allof my
43 years that pop up on the market before I can finish my prototype. I started
writeing them up and mailing them certified mail with return reciept to myself.I
have a file cabnet full, waiting to pounce. This seems to put a stop to it! This
legally establishes date through US mail. I believe "thoughts" enter the
universal "mind" "out there".  Did I really think of it, or did I tap into the
"universal" ???? What can "we" really do if all "tuned in" to the same thing???
