Thanks Bernie and Roel
My ISP is Plusnet and they have a feature where you can keep a check on your usage aty any time just by clicking on the members centre.
This is useful when you ae coming to the end of a month when you want to download something big. Better to wait a couple of days before downloading something really big or you incur an extra payment. Having said that, the extra payment is absolutely minimal, like only £1.25 ($2) for an extra 1GB.So who cares anyway?

cheers
