And I'm still put off by the complete absence of any person's name on the site and in their email messages. The people behind it might be the nicest people in the world with only the purest of intentions, but they're not making it seem that way. I'm still very nervous about this one.

It seems to me there was their representative and there is the address on their site. All is opened. Or it is not enough for you?

I am new in this business, but they have called in me confidence. It is too much work and money to be swindle. 

I have uploaded my photos and received money in my account. I am so happy. It is my first money in this business 
However, I have not enough photos to receiving 100$.

I still the beginner in this business, but even I would not began to upload photo and waste time for a site, which does not know how sell my photo. Tell about yours plan, please.

This information was necessary to me. Thanks
