Educating Internet to the People

One of quickest way to educate the people is enabling them to the source. Another source of education is internet with all of its advantages and disadvantages. Since I open my cybercafe for student and public access, I got so many experiences and troubles, each of them is p*rnography. I'm not an IT expert but how to block this trouble? I can't hire a sysadmin because of financial problem. Based on this condition the searching and learning were began. "Trial and Error" is best teacher for the novice on this field. Finally, I use OpenDNS and Squid Blocking to face this problem. Although they were not solving my problem completely (because some local p*rnsite and flashsite can't be blocked and I believe my configuration have not perfect yet) I felt happy because I start it from a big zero. Just one thing, learning by doing, you will get the suitable experience and knowledge for you. Lately I got another problem, how to re-invite my cybercafe visitor which gone caused by p*rnsite blocking. This will be a marketing lesson. Happy learn!
