managing whitelist for entire school?
This is my first question on here, i work as an IT Technician at a High School. We have been running a very successful whitelist on the computer rooms over lunch and break(cut behaviour problems in half, and now we actually have kids working over lunch!:D), however now we wish to expand and push the whitelist for students over the entire day. Now here is the gothca bit we dont have enough time to manage a whitelist and keep it up-to-date at a realtime level, so we would like to give teachers access to the list so they can add websites as required, the end goal being having a list of sites so large that the kids are not restricted enough to prevent them working but they do not have access to any games...
Currently we run ISA Server 2004..
Do any of you have a similiar set-up to what we are looking for or can recommend any programs that could sit over the top of ISA, allowing teachers to add there own websites?
