4 years ago, altho ive taken many "breaks" in that time. it all started when i joined a clan and one of the guys in it made tags and i wanted to learn.
in August of '05 (started with PS CS), took a break in March - August of the following year, then bought PS CS2 and started again in late '06.
Two years ago, I was on a forum where we hung out and played games on Xbox live...bunch of the guys were using photoshop so I joined them.
I think we already had a topic like this... Oh, found it... http://www.gamerenders.com/forum/index.php?showtopic=302762
