Hey Savannah! Welcome to YWS! We're a really great bunch. Admittedly, we're a little strange at times, but I'm sure you'll fit in just fine.
As for making a good start, there are loads of ways to do so. A great way to get to know people is by logging into YWS chat. You can chat freely with everyone there, and it's an awesome way of making friends. The chat room is on the homepage, so it's easy enough to find. You should check that out.
Searching around the forums and reviewing are another few great places to start. People just love it when you review their work. In fact, what kind of reading and writing are you into?
It's great to meet you, Savannah, and I really hope you enjoy spending time on the site.
See you around!
xoxo Skins
