Welcome to the site... be care free and stay away from the penguins. They bite.
As I too was once new here I can only begin to think how much I have changed in my writing and my work since coming here. Don't be afriad to ask for advice or give some. No advice is bad, just perhaps not useable.
I recommend reading a few of the articles up first check out the Advice codex located here. Citadel Advice
There are many more good articles to read from to get ideas for better submissions, better writing, as well as better campaign management. You name it you can probably find it here. And if not, put it up for all to read.
Glad to see a fresh face, oh and I'll take a peak at what you've got there.
