Is there somewhere I can go for basic Turnitin questions? I am new to the platform, and I can't figure how to do simple things like: 

1) Adding my co-teacher

2) Creating my own rubric - I can do it, but it is cumbersome and difficult for the students to read

3) Copying assignments from class to class without recreating them for each class

Just looking for a beginner's guide or something like that - I am the lead teacher at our school, and I would like to know more so I can help my team.
