Thanks Martin. I was not aware of other systems (or even of this one) until I had a problem and got it sorted. This is a system that can be used by anybody, so I don't think that spying comes into it. I thought that perhaps some one that was having problems configuring their machine might benefit from a more experienced
site member being able to access their config files etc and help resolve problems. The security system requires the password to be given on each session (by telephone)and is automatically changed as soon as that session is ended. I have used it three times now and have found it very useful. Obviously it goes without saying (but Ive said it anyway) you would only give your password to someone you trust!! G.
