You answered your own question - you haven't done ANYTHING. How do you expect to be found? You have to advertise. There is plenty of information in the forums on the site on how to do that. If you upload and sit, that's all your doing. You have to tell people you exist. The site only prints the work. This is also the wrong place to ask this, ask in the site and you'll get a flood of answers. I also can't say much here because i need to see the quality of your work, is it well presented? Do you have keywords, descriptions, are you adding work all the time? Do you have social connections and so on. Its a lot of work.

Read my review of FAA which I just posted. None of the advice people give on the forums is going to get you noticed, because the site is simply TOO BIG. They are either going to blame your work itself for not getting noticed (nice! - not), or they're going to tell you to do this and that, make you spend a lot of money, etc. and you will still get nowhere. They cater to the already well-known and famous. It's baloney. Find a different site. Personally, I'm going to Artspan. It's smaller and I was surprised to see that for what I do I don't have to compete for attention with thousands upon thousands of other artists. They also state that they care about the artists that join. I hope so - because I don't think FAA does - unless, again, you're famous.
