Being an honest type of bloke, and being aware they'd catch up with me anyway, I thought I'd better report it. Their technician, probably in Rangoon, advises me that I have no usage readings because my modem is not connected. This makes my present on-line status strange. So, until they send a man around to peer into the nearest cable box, I am on unlimited megabytes...
While I consider the possibilities of this, I am currently ripping into 130 MB of Glacier Bay scenery as recommended in the posts.
I wonder how long it will take them to send out a tech....especially since it's costing them in this instance.

No discussion of piracy please!
