Situtation is thus:- live in shared house at the moment and the 'master' PC (actually an Apple) that governs the wireless network and had the router attached, is someone elses. It is secure as far as the outside world is concerned... atleast as secure as needs be. That isnt the issue. We dont share files, resources or printers - merely the wireless connection. With this passing through (well sort of - you know what I mean) someone else's machine - can they see what I do, what sites I visit, what I type on those sites, etc.... and is the same for using any of the MSN messenger type programmes? If it's a case that they could do it and find out all this stuff if they were a bit of a techy wizard and installed some programmes etc - then I am not worried, just dont want them to be able to click a folder and see my whole web history and typing as easily as all that. God, want to be able to occasionally stumble upon MILFS Go Wild without facing the giggles over breakfast!!
