Is this your first time here?
Your user name is a combination of the first letter only of your last name PLUS your whole first name, with no space between last initial and first name.
So, if you are Rachel Jones, your username would be jrachel.
Your password is your lunch number. Find this on your schedule and write it down! Do NOT share it with anyone else!
Sometimes, users have the same username as other students and it will stop you from logging in. If you are absolutely sure you logged in correctly, tell the teacher.
