Hi, mu2zen, and welcome to Deviant Art.
I hope that you have a lot of fun here.
There is plenty to do, whether you enjoy being a member of a group or, like me, just tend to do your own thing. If you like being in groups, there are a large number which cater to pretty well all tastes. If not, and you want to become known, then I suggest that you visit other people's sites and leave comments and remarks in them. Giving llamas and going on people's "Watch" lists (if the art is to your liking) is also a good way of meeting people.
If you have any questions or queries, please feel free to ask, or go on to the forums which are available on site.
Whatever you do, just have fun.
All the best,
