As for general use, are you traveling a lot? Employees that travel tend to have a bit more leeway with the use of their PC, browsing should be no big deal, but I would still recommend not loading up games or media on it. Get a smartphone or 2nd PC for that. And have some common sense; no porn browsing, period.
OT: sounds like there are a lot of 'bosses' on this thread
really this thread is 'over in 1', as I totally agree with the initial comment. Ad-hoc servers on the net, you're lucky they don't give it and you the boot.
At my current job tho, people hate being left out of the loop, so reply-alls are the norm, rather than the exception. "Think before typing" hasn't been repealed, people just act like it has.
