Any Eyeka.com Members Here?

I have recently discovered the Eyeka website (www.eyeka.com) and quite like the idea of joining. I was wondering if there are any Eyeka members on POTN, and if so, what do you think of the site?

I have been right through the Terms & Conditions document (http://en.eyeka.com/le​gal/terms) and the only thing I didn't like the look of was this bit in Section 7, Pricing Conditions and payment of Contributors:

'The Contributor allows Eyeka, in his name and on his behalf, to open an escrow account of the amounts received, from a banking institution chosen by Eyeka.'

Also, they want contributors to upload the full size versions of photograph files, which I suppose is due to how customers would buy images, but nevertheless I don't like the idea of uploading full-size image files of anything to the internet.

Any comments or observations would be interesting to hear.

Thanks

Mike
