OK.... I'll give you some tips
Just cos I am that kind of gal...
All the links you need are the white writing at the top... click on "Forums" and it will give you the list of forums, most of the action happens in Chit Chat.. some in nasty.
The first thing I do, is click on the "new posts tag" It gives you all the new posts since you were last here... you can get to that, by going to "Quick links" then clicking on "new posts" OR becuase Kall is so wonderful, you can just click "New posts" up the top (theres a little blue link up the top by your private messages and points).
This lists all the new posts from any forum that you have permission to see, and you can go through like that.
Theres journals you can look at and comment on... just click the journal link and follow your nose, same with the gallery.
You get points for posting and for the many messages you will get in a thread you start. You can use these points to gamble with 9Raine loves doin that!) or to use in the store (you can do cool things like change other poeples custom titles, change your user name to colour...)
Anything else, just ask!
