Help with Assassin build

Hi, i've just started playing an assassin and can anybody please give me some common/popular builds on getting started in PvP and PvE?

I've heard bits about "Rage sins" and "Knockdown Sins"
but i don't know what they mean. Is it possible for anyone to post me a full 8 bar skill to get me started please?

thnx There are various places where you can find pre-made builds such as THE STICKY THREAD IN THE ASSASSIN SECTION. be wary of out-of-date builds though I guess.

Seriously, the best way to learn a class is to create a build yourself, post it here, and have help improving it.
