Most institutions have (or should have) some kind of harassment policy as well as guidelines on appropriate usage of facilities. This is surely more appropriate than relying on software which is of variable and contentious effect. The fact that we have CyberPatrol installed at my institution does not mean that my colleagues have not extracted pornographic printouts from the student printer, or had to break up groups of giggling twenty year olds delighted by dubious email attachments. On the 'accidental' issue (i.e. coming across offensive material by mistake), proper education in Internet usage should surely help. Instances I've come across of this happening have been with people not aware of the importance, after using a search engine, of looking at a URL and what's printed below it before merrily clicking away. Hate sites, like pornography, mostly seem to advertise themselves. Chloe Stewart The Learning Resource Centre Kings Road Reading College and School of Arts & Design Reading RG1 2HJ (0118) 967 5078
