You are going to find a lot of pros slipping in soon. The one thing you will eventually realize is that buyers don't necessarily look on the forum for starving photogs. So competition is going to become fierce, and you will have to do some marketing work on your own. I don't think the robots are picking up our keywords/taggs on this site just yet. Actually I don't expect to sell anything for at least a year. By then Google will probably have us in their sites.
Just keep uploading your best work; someday you will be discovered by willing buyers. Till then - good luck!
