mmm I was about your age when I started tinkin around with Websites...it's never too early to learn!
First, you need a domain. Godaddy is good for domain registrations. (not hosting..see "next")
Next, you need hosting. 1&1 is cheap and does the trick.
Now - you gotta build your site! woohoo! the fun part
Photoshop isn't exactly at everyones fingertips. Yeah - you can download the 30 day trial, but it will take you months to learn it. Go with Gimp for now for your graphics (oh yeah, you already have Gimp...for your logo!!...i'll leave that note in there for others)
Think of Websites like...a Car.
You have your designers that design the outside and make the car pretty (graphics)...and then you have your engineers that make what's under the hood!! (the code) that's the part that matters the mostof course, I'm biased because I'm a web developer.
You need to learn HTML first. Then CSS. That should get you going in the right direction![]()
