Luke,
Not entirely true.
As long as the computer you are using has Java Work Environment on it, you should be fine.
I'm not for anyone slacking off at work, being on the Net, but as far as I am aware it is not a script that allows you into Chatrooms.
As long as your cookies are "true" with the ECN server, you shouldn't have a problem.
BTW, Scripts are what hackers use to take over computers.
Javascript has little to do with it.
