The trouble with "self policing" is that different people have different ideas about what is work safe. And different work places have different ideas about levels of acceptability.
I've been caught out before on other forums by threads that insisted that they were work safe but turned out not to be.
I am able to get some forums at work, whilst others are blocked.
So, keep up the amusing smut - I'm all for it! But don't drop me in it at work please.
