I have been making GFX's for a little over 3 years now.I am only 16 but I know that I want a job as a graphic/web designer. I am really into making sigs and editing websites/forums.
I have had my own forums that didn't make it. The best forum I have made lasted 5 months and had around 500 users. But all of a sudden everyone decide to stop posting there so I shut it down.
