For those interested and want it I have made up a program that will keep track of your usage if you use https://www.telstraclear.co.nz/usagemeter/index.cfm as your usage meter.
It works very much like TUC but keeps it's setting in the registry. It encrypts the password using TrippleDES so it cannot be seen in the registry. It runs as a window or your can have it so it goes straight to the IconTray.
It is written in VB.net 2003 so needs the .net 1.1 framework for it to work. The program is only 84K in size with no install as yet as I have not got round to that bit yet. I just created a directory on my PC and copied the files (2) and ran it from there.
If you want to try it out (works for me but is still only just done) then PM me with your e-mail address and I will send it to you.
May be adding additonal features in future such as other ISP's but need to get it working for me first.
