New to M:EE, I have a couple of questions.

Hello!

I am creating a world for my students, and I understand that students have to enter a code to join my world.

My question is, will they have access to the world tomorrow when I host again, without having to enter a new code?

Also, I had a student who simply could not join, it said "unable to connect to the world". 

Is there another way to join other than entering the code?

Other than that, students really enjoyed their experience today! 

Thank you.
