Anyone here use PhotoShelter?

I’m not sure if I got the right forum for this, please move if there’s a better home for it.

Has anyone here used PhotoShelter.com to sell or license your digital photography? I’ve read in a few places that it’s possible to make a few bucks doing this if you take decent enough pictures of the right things.

It’s free to sign up, but if you want to sell you have to shell out $50 to have them set up a merchant account for you so you can accept credit cards. Not sure if it’s worth it or not.

Anyone here do it? If so, how has it worked out for you?
