I know what you mean but unfortunately I think our 'privacy' is a thing of the past. After all it is not only commerce that tracks us but our respective governments too, from using an ATM to debit/credit card transactions, customs/passport control, CCTV (we in the uk have the highest number of CCTV cameras per head of population) it is said in the UK that we can be monitored from start to finish of a journey, beginning with the booking of a ticket or filling up with fuel, to of course the dear old internet, isp's, email etc. I know in the UK, France, the USA and Australia in particular (sure MANY other countries) all have joined forces and monitor every bit of voice & data in and out of the country and share the information gathered. My point being I suppose, is it worth the effort trying to remain anonymous any more? I think it is a battle we have lost, maybe embrace it instead and find a way to use it to our advantage as well. (Then again everyone says I'm a dreamer haha)
@Cobra you have hit on why my nickname (not so ) Lucky lol. I HAVE the mentioned GE Glow Lamp Manual in PDF format if anyone wants it by the way ;) Can it be uploaded to the group somehow? Google docs maybe? &/or I will email anyone who wants it for FREE. Dave.
