Is Stockbo still around? 

The site is still in existence. Beyond that, I couldn't say.

Sean never had any files there - there was much jesting around here when they made him "featured" for having created an account.

From October 30, 2014 e-mail they sent out:

"After a recent meeting between the directors of Stockbo, we have decided that we will offer the business for sale. The reason for this is due to a lack of time between all of us to take Stockbo to where it deserves to be. This was a difficult decision to make for all of us but we believe it is in the best interests for Stockbo moving forward, for the vision and for our beloved members and photographers.

We are currently in talks with some parties in Perth that may be interested in acquiring the business. Regardless of who acquires the business, we plan to ensure that the current terms and conditions that we have set out during this amazing journey will be upheld. Our number one priority has always been providing a platform focused towards fairness for our valued photographers, something that we hold dear to our hearts.

If any of you would be interested to take command of this business, please get in touch with us via email or simply send us a private message on our Facebook page.

We would like to express our gratitude for all of your efforts in making Stockbo what it is today. Without your fabulous contributions, Stockbo would just be a plain stock platform like many that exist today.'

They state $5 gross revenue and one of my images sold for $2.50 so I make up 50% of their entire revenue- now I feel like a VIP 

4000 images, they're really taking it to the big boys.

I'm glad they rejected 4/5 of my best sellers that I uploaded there. If they'd accepted them I would have wasted many hours uploading the rest of my portfolio.

Interesting that the cost per month they quote to keep the site running.
Shows that with some sales each month (after development etc is stopped) the small sites can still make money for the owners, but not much for contributors.

A very long time ago I uploaded one file to se  how it works. It doesn't work at all
