Welcome!
We always recommend newbies take some time to read a few stories before diving into their own projects, so sounds like you're on the right track. If you could also rate anything you read and leave at least a short comment, that would be wonderful. Lots of attention starved authors around here, and the more ratings the easier it is for the site to rank the stories...plus the more stories rated the more points you collect, meaning your ratings start being weighted more and having more of an effect.
Have fun, and let us know if you have any questions.
