A big warm welcome to you Theo.
These forums are wonderful for us tea-enthusiasts, they allow us to address (and ask), questions from the strict basics to the wildly TEAoretical.
Search through our forums for any of your questions, if you can't find something, throw up a post and we'll share our knowledge.
I encourage you as well to drop by the chat room (it will appear as a small "instant messenger" box on the right). Me and many other enthusiasts take up post there, and we can answer most of the questions that you can ask.
Everybody has their own style, you may like exclusively black teas, while some folks such as myself drink primarily green, Japanese green, Sencha Fukamushi green.
You have opened the door to the world of tea. We welcome you.
