Oh, yes, it's fine!
The reason we asked where you were is for a couple of reasons- one is to make sure you are here legally. We ask all brewers to be of legal age in the country they reside it, so they can participate in the forum.
The other reason is because there are a LOT of different kits and ingredients available depending on where you live. Some of the items I use you'd likely not get in the UK. We do have other brewers here from the UK, and they could be much more helpful than I can with ingredients.
Here's a good place to start: howtobrew.com. That will help with the basics of how to begin. Also, our wiki has great info.
Feel free to ask any questions and look around a bit.
