Well, this belongs in the New Member's Board section, but I'm sure it will get moved there as soon as a mod sees it, so for now...
Check out the
Newbies' Guide to the Universe
It can be a big help to new members. Also, read the rules [there's a link to them at the top of your screen]
That covers the basics. Other than that, just have fun posting! Get to know people and become a regular member here :]
Hope you enjoy your ZU expierence!
