Hello to you as well. Your grammar and such seems great, so that already elevates you past the average "Hello, I'm new" person. :)
Since you made your account today, here's a few things about this site and/or as a general intro:
1. This is a great place for writing and receiving feedback. The members here are very straightforward with their critiques, but I find them to be very helpful.
2. Read some of the highest rated and some of the newest storygames. The best are what the site likes (obviously) and the newest show what to do and what not to do as a writer. Be sure to rate them as well.
3. Review the newest storygames if you have time. It's for the same reasons as #2, but it also simply helps the site.
4. The forums have their own flavor. It's fine if you don't mind the occasional fool and if you can take what people say in stride.
Anyway, I normally don't greet people, but you look quite good. I hope you'll stick around. In Help & Info, there's a bunch of helpful (and some "meh") articles. The Website section will probably answer most questions you have for the website (obviously). Have a nice day!
Others have already covered the basics, so I guess I'll just welcome you to the site. :)
Welcome. May your stay be pleasant.
