Re: hello everyone
tuck your head on foreward ukemi :-)
but then you would be told that, and if not, you would learn it quickly....
Bow when you enter the dojo.
Bow every time you enter or leave the mat.
Rush to grab a broom to sweep the mat at the end of class. (follow the other students)
Sit at the end of the line until someone higher up in the dojo tells you otherwise :-)
When in doubt, bow and say "o-ne-ga-shu-mas" (phonetic spelling)
oh, and most importantly....
Don't sit with your back to the shoman (alter like place in the dojo, usually with a picture of an old japanese guy aka O'Sensei, founder of the art) Very bad form.
Best of luck in your training...
