I was 15 when i joined as well. However, the entire team was alot younger then. Now we all have grown up a bit, and have stayed close.
Learn Photoshop! Learn to have all your thoughts in a single post. Learn how this team operates, and who is in control of what. Stick around, you never know what could happen. But as of now, Ill put an end to this thread and say that your not ready at the current moment.
Side note; This team started when most of us where around the age of 15-20, that was, 6 years ago (for me). However, the core group of developers stuck together, and now 6 years later, all of our work has improved, exponentially .
