Dojo Etiquette 101

This post is long overdue.
As Sammy has pointed out,we've had a huge influx of beginners who do not know
dojo etiquette and I felt it's important to point out a few basics:

1)Punctuality-always try to try to the class before the teacher.
In case you are late,sit in seiza at the class entrance and wait for the teacher's permission to enter.
Make sure you warm up if you find the warm-up session is over.

2)Take off all jewellery before class,this includes but is not limited to rings,bangles,bracelets,earrings,
anklets,chains,chokers and necklaces

3)No chewing of gum or snacking during class

4)Maintain silence.

5)Leave your ego at the door
