To be honest David, I'm not sure i've even found my forte yet!
I'm currently running this website (obviously) and I have a few other projects starting, one being a webhosting newsletter and the other a traffic supplier (I ran one before last year before selling it for a few thousand). I'm getting into web development and i'm also a keen graphic designer, just working on a banner for a contest at the moment.
My first major success was
www.banners2go.com, you can see some of my work there. I'm also learning alot about search engine optimization and have a real passion for online and offline marketing especially viral marketing.
