Nice to see your rush of enthusiasm Tina. Yes, it's amazing what can happen at SS.
I joined SS only about a month ago at the strong suggestion of Tom from this forum. I've managed to upload about 150 images with only 7 rejections, so all the worries about quality, noise etc simply aren't there (well not for me anyway).
Even more remarkable is that in my first month I have had 734 sales. Yes, I know that sounds ridiculous and I wouldn't have believed it if I hadn't seen it with my own eyes.
Someone on the SS forums made the comment 'SS is the only place where a contributor can get an immediate sense of success'. A good and valid comment I think.
Good luck and keep uploading to SS regularly.
