Basic operation guide

1. On the website, should there be a part like control guide?

2. In game, press f1 should give a guide too.

Currently I am still frustrated by the purple whispers -- because I don't know how to answer. I guess /w in chat box, but what if two ppl whisper me.

On the other hand, I tried lots of keys and can not see my cross hair change.

They should be documented, right ?

Maybe someone can help me here.
