Despite being of an age where I should, I don't understand some of the jargon involved in this business. What's a cookie? Also, how does one personal message someone? Doesn't really matter now, but in 2 weeks I'm going to uni at York, and want to take advantage of the unlimited internet access. Lastly, and most importantly, how do I stop being a guest? Do I have to register or something? Please, someone who is technologically minded, help. Cheers, Kit
