Did you come to know about it through a person you know, a Google search, an ad, a website, etc.?
I came to know about Envato through someone I know.
My story begins in a dark and misty time, now known as January 2010.
I was looking for somewhere to sell music which I made mostly just for fun. I searched around for a while and couldn’t find an audio library site which seemed right for me. Then I just happened to see a banner for Audio Jungle on my friends website (he sadly hadn’t thought of telling me about it). I clicked it and knew pretty quickly that I had found the right place for my music. It just seemed a cool site, and different to any other stock sites.
Just like KingDog I found FreelanceSwitch when I was setting up as a freelancer, and ended up clicking through to the marketplaces. Changed my life very quickly.
I know about the Envato websites back in the days when I was learning Photoshop and came across PSDTUTS . Later on I found out the other great sites they have and fell in love True Love Story
I learned about Envato Marketplaces from Designer_things. He was looking for new stocks for selling vectors.
