Steve,
Your with Tiscali so your fucked mate 100%....I'm in the middle of switching from them as they say in the terms and conditions somewhere that they do not support any p2p/newsgroups and when your found will restrict the cunt outta you.... (also think not 100% but depending on how much you download 80GB seems to be the "oh we have noticed you and gonna cut your speeds like fuck" mark

)
The only time i max my speed out is anything between 11pm-1am until 6am-10am but it changes week to week.
Also the same as you the first little while i was smashing it and downloaded something like 220-280GB the first month
Look it up on google mate
As a side note, how you doing bud?
Mart
